ARM Introduces Mali-C71 ISP (Image Signal Processor) for Automotive Applications

April 25th, 2017 No comments

A camera in an embedded system is normally connected to an ISP (image signal processing) block inside an SoC to handle the data coming from the sensor, and with recent cars now requiring more and more cameras for car DVRs, car parking systems, and self-driving vehicles, ARM has now unveiled Mali-C71 ISP specifically designed for automotive applications with support for 4 real-time cameras and 16 camera streams with a single pipeline.

ARM explains that you can’t simply use smartphone cameras in automobile, as automotive requirements in terms of clarity and reliability are much more stringent. For example, Mali-C71 supports UWDR (Ultra-wide dynamic range) up to 24 stops, against 15 stops for the best DSLR cameras, which removes noise and process multiple exposures from the camera, and allows the processor/computer vision engine to detect objects such as a pedestrian, while others systems may not detect it. The image is also much clearer to the driver when displayed on a rearview mirror or other displays.

Flint OS is a Chromium OS Build for Raspberry Pi & Firefly-RK3288 Boards

April 25th, 2017 4 comments

Chromium OS for SBC aimed to bring Chromium operating systems to low cost development boards such as the Raspberry Pi 3 board, but the website is now down, and the developer announced he had stopped working on it several months ago due the hardware limitations of the Raspberry Pi 3 board. But others decided it was still worth the effort, and created Flint Innovation company (based in UK/China) to develop Flint OS, a build of Chromium OS with optimizations for Raspberry Pi 3 and Firefly-RK3288 boards with more boards likely coming soon.

Click to Enlarge

The developers also provide an x86 image, but after asking more details, it turns out they only changed the boot splash screen for now on the x86 image, with most of the early work done on Raspberry Pi board:

At this moment our public Flint OS releases are still pretty much vanilla Chromium OS (we changed the boot splash screen). Our efforts so far have been focused on getting Chromium OS to run on more hardware platforms other than Google approved ones, with a special focus on ARM-based embedded systems. This is also why we found your site 🙂
Flint is still at its very early stage, going forward we plan to bring enhancements for the application layer too. For starters, we have planed to modify the activation/authentication mechanism that Google has built-in for only allowing Google account login.

If you’d like to give it a try, head to the download page for either:

  • Flint OS for RPi v0.2.1 “Beetle” image based on Chromium 55
  • Flint OS for PC v0.2.1 based on Chromium 55

They also have a Flint OS for Firefly-RK3288 v0.1 based on Chromium 57 in their Chinese download page, and uploaded a short demo with HTML5 video playback in YouTube. The image can be flashed to a USB drive or micro SD card with Etcher, Win32DiskImager, or other common tools.

A build working with VMWare/VirtualBox is also in the works, but there are still some blockers with regards to the graphics driver. Note that while Chromium OS itself is open source, and Flint Innovation intends to comply with open source licenses (GPL and others), Flint OS is not fully open source, and the company offers consulting & customization services, as well as IT-as-a-Service for schools and businesses.

Azul Systems’ Zulu Embedded is a Build of OpenJDK for ARM, MIPS, PowerPC, and x86 Compliant with Java SE standard

April 6th, 2017 3 comments

Yesterday as I wrote about the Embedded Systems Conference 2017 schedule I came across a potentially interesting talk entitled “Building A Brain With Raspberry Pi and Zulu Embedded JVM” by Azul Systems that will explain how to build a brain emulator using a cluster of Raspberry Pi boards. I wanted to find more about it, but I have not been able to find any details about the project/demo at this stage. However, I could still learn a bit more about Zulu Embedded, which is said to be an open source Java Virtual Machine based on OpenJDK, compliant with Java SE standard, working on 32-bit & 64-bit ARM & x86, MIPS, and PowerPC, as well as  multiple operating systems.

Some of the key features of Zulu Embedded include:

  • Java Support – Java 6, 7, 8, and 9 when available
  • Java Configurations – Headless, headful, or compact Java Compact Profiles
  • Hardware – ARMv7 and 32-bit ARMv8, ARM64, Intel/AMD x86, 32-bit and 64-bit, MIPS, and PowerPC
  • Platforms & Operating Systems
    • Linux 32/64-bit – RHEL 5.2+, 6 & 7 or later, SLES 11 sp1/2/3, 12, CentOS 5.2+, 6 & 7 or later, Ubuntu 10.04, 12.04, 14.04 & 16.04, Debian Wheezy & Jessie, Wind River Linux, and Oracle Linux
    • Windows 32/64-bit – Windows 7, 8, 8.1, 10/IoT/Mobile, 2008 R2, 2012, 2012R2, Nano
    • Mac OS X
    • Hypervisors – VMware, Hyper-V, KVM
    • Cloud – Azure, AWS, Google, Snappy, Docker
  • Packages – ZIP, MSI and DEB are available. Custom packages on request.
  • Memory Footprint – 11 MB to 250+ MB

Some of the advantage of Zulu Embedded is that it is 100% open source released under GPLv2 with Classpath Exception (I could not find the source code however), and fully certified and compliant with OpenJDK community technology compatibility kit (TCK) from Oracle.

Zulu Embedded is free to download for ARM Linux 32-bit (hard and soft float), and x86 Windows & Linux 64-bit, as well as x86 Windows 10 IoT Core 32-bit for MinnowBoard MAX. You’ll need to contact the company for other configurations.

It’s been used in program such as openHab 2.0, which replaced Oracle JDK with Zulu Embedded JDK, since it can be freely redistributed (no licenses required), and performance and stability feels exactly the same according to comments on Github. One person explained how to install it on the Raspberry Pi board (note: early access program is not needed anymore, since the binary has been publicly released), and the installation procedure is just the same as with OpenJDK.

You can visit Zulu Embedded product page for more information.

  • 09:00 – 09:45 – Understanding the ARM Processor Roadmap by Bob Boys,   Product Manager, ARM

In 2008, the ARM processor ranged from the 32-bit ARM7 to the Cortex-A9. There were only three Cortex-M processors. Today the roadmap has extended up to the huge 64-bit Cortex-A72, down to the tiny Cortex-M0 and out to include in the winter 2016, the new Trustzone for ARMv8-M.

The ARM roadmap, in order to effectively service many markets, has grown rather complicated. This presentation will explain the ARM roadmap and offer insights into its features. Questions answered include where processors should be used and sometimes where it makes more sense to use a different processor as well as different instruction and core feature sets.

This will start at ARM 7 TDMI and how and why ARM turned into the Cortex family. Each of the three components: Application (Cortex-A), Real-Time (Cortex-R) and Microcontroller (Cortex-M) will be explained in turn.

  • 10:00 – 10:45 – Mixed Signal Analysis: digital, analog and RF by Mike Borsch,  Application Engineer, Rohde & Schwarz

Embedded systems increasingly employ both digital, analog and RF signals. Debugging and analyzing these systems can be challenging in that one needs to measure a number of different signals in one or more domains simultaneously and with tight time synchronization. This session will discuss how a digital oscilloscope can be used to effectively debug these systems, and some of the instrumentation challenges that go along with this.

  • 15:00 – 15:45 – Building A Brain With Raspberry Pi and Zulu Embedded JVM by Simon Ritter, Deputy CTO, Azul Systems

Machine and deep learning are very hot topics in the world of IT at the moment with many projects focusing on analyzing big data to make ‘intelligent’ decisions.

In this session, we’ll use a cluster of Raspberry Pis running Azul’s Zulu embedded JVM to build our very own brain. This will use a variety of programming techniques and open source libraries to emulate a brain in learning and adapting to data that is provided to it to solve problems. Since the Raspberry Pi makes connecting sensors straightforward we’ll include some of these to provide external stimulus to our artificial brain.

We’ll conclude with a demonstration of our brain in action learning and adapting to a variety of input data.

  • 16:00 – 16:45 – Vulnerabilities in IoT: Insecure Design Patterns and Steps to Improving Device Security by M. Carlton, VP of Research, Senrio

This talk will explore vulnerabilities resulting from insecure design patterns in internet-connected embedded devices using real-world examples. In the course of our research, we have observed a pattern of vendors incorporating remote configuration services, neglecting tamper proofing, and rampantly re-using code. We will explore how these design flaws resulted in vulnerabilities in a remote power supply, a web camera, and a router. This talk is intended for a wide audience, as these insecure design patterns exist across industries and market segments. Attendees will get an inside view into how attackers operate and walk away with an understanding of what must be done to improve the security of embedded devices.

  • 08:00 – 08:45 – Heterogeneous Software Architecture with OpenAMP by Shaun Purvis, Embedded Systems Specialist, Hardent

Single, high-performance embedded processors are often not adequate to meet today’s system-on-chip (SoC) demands for sustained high-performance and efficiency. As a result, chips increasingly feature multiple processor types to deliver flexible compute power, real-time features and energy conservation requirements. These so called heterogeneous multiprocessor devices yield an extremely robust SoC, but also require a more complex software architecture capable of orchestrating multiple dissimilar processors.

This technical session introduces the OpenAMP software framework designed to facilitate asynchronous multiprocessing (AMP) in a vendor agnostic manner. OpenAMP can be leveraged to run different software platforms concurrently, such as Linux and an RTOS, on different processors within the same SoC whether homogeneous (multi-core), or heterogeneous (multi-processor), or a combination of both.

  • 09:00 – 09:45 – How to Build Products Using Open Platform Firmware by Brian Richardson,  Technical Evangelist, Intel Corporation

Open hardware platforms are great reference designs, but they’re often not considered “product ready” due to debug features built into the firmware… but a few firmware changes can turn an open hardware board into a production-quality platform.

This session demonstrates how to optimize firmware for product delivery, using the MinnowBoard Max as a practical example, by disabling debug interfaces and optimizing the platform for an embedded software payload. Examples are also given for enabling signed firmware updates and secure firmware recovery, based on industry standard UEFI firmware.

  • 10:00 – 10:45 – Understanding Modern Flash Memory Systems by Thomas McCormick, Chief Engineer/Technologist, Swissbit

This session presents an in-depth look at the internals of modern flash memory systems. Specific focus is given to technologies that enable current generations of flash memory, both SLC and MLC, using < 30 nm process technologies to provide reliable code and data storage in embedded computer applications.

  • 11:00 – 11:45 – Implementing Secure Software Systems on ARMv8-M Microcontrollers by Chris Shore,  Director, Technical Marketing, ARM

Microcontrollers incorporating ARM TrustZone technology for ARMv8-M are here!. Now, software engineers developing on ARM Cortex-M processors have access to a level of hardware security which has not been available before. These features that a clear separation between secure and non-secure code, secure and non-secure data.

This presentation shows how software developers can write secure code which takes advantage of new hardware features in the architecture, drastically reducing the attack surface. Writing software carefully builds on those hardware features, avoiding bugs and/or holes which could compromise the system.

  • 12:00 – 12:30 – Keynote: State of the Medical Device Industry by Frost & Sullivan
  • 13:00 – 13:45 – Enabling the Next Era of Human Space Exploration by Jason Crusan, Director of the Advanced Exploration Systems Division within the Human Exploration and Operations Mission Directorate, NASA

Innovative technologies, simulations and software platforms related to crew and robotic autonomous operations, logistics management, vehicle systems automation, and life support systems management are being developed. This talk will outline the pioneering approaches that AES is using to develop prototype systems, advance key capabilities, and validate operational concepts for future human missions beyond Earth orbit.

  • 14:00 – 14:45 – Common Mistakes by Embedded System Designers: What They Are and How to Fix Them by Craig Hillman, CEO, DfR Solutions

Embedded system design is a multilevel engineering exercise. It requires synergy between software, electrical and mechanical engineers with the goal to create a system that meets customer requirements while remaining within budget and on time.

The propagation of embedded systems has been extremely successful. Many appliances today contain embedded systems. As an example, many fuel pumps contain single board computers whose sole purpose is credit transactions. Some companies doing positive train control (PTC) use ARM/RISC and ATOM based computer modules. And embedded systems are currently dominating the Internet of Things (IoT) space (ex. mobile gateways).

However, all of this success can tend to mask the challenges of designing a successful embedded system. These challenges are expected to increase dramatically with the integration of embedded systems into IoT applications, where environments can be much more severe than standard home / office installations.

This course presents the fundamentals of designing a reliable embedded device and the most common pitfalls encountered by the system designer.

  • 15:00 – 15:45 – Porting to 64-bit on ARM by Chris Shore, Director, Technical Marketing, ARM

The ARMv8-A architecture introduces 64-bit capability to the most widely used embedded architecture in the world today. Products built to this architecture are now mainstream and widely available. While they are capable of running legacy 32-bit software without recompilation, clearly developers will want to make maximum use of the increased and expanded capability offered by these processors.

This presentation examines the steps necessary in porting current 32-bit ARM software to the new 64-bit execution state. I will cover C porting, assembly language porting and implementation of hand-coded SIMD routines.

FriendlyELEC Introduces $12.99 1-bay NAS Dock Kit for NanoPi NEO Board

April 3rd, 2017 26 comments

NanoPi NEO is a tiny board with Fast Ethernet and USB 2.0 interface, so in theory it could make a nice low-end NAS as long as you don’t need the best performance. As always the problem is that there was no case for it, but FriendlyELEC changes that as they just launched a 1-bay NAS Dock Kit for NanoPi NEO board selling for just $12.99 (promotional price at launch).

The kit comes with the following:

  • 1-bay NAS Dock expansion board with
    • JMicron JM20329 USB to SATA bridge
    • SATA connector for 2.5″ HDD drive
    • Extra USB host port
    • On/off switch, and dual color status LED
    • Header to connect NanoPi NEO board
    • 12V DC power input
    • Dimensions – 151 x 89.7 mm
  • NS-120 aluminum enclosure (154 x 100 x 47.5 mm, 4141 grams)
  • Heatsink set for NanoPI NEO
  • M3 6mm screws, M2.5 6 mm screws
  • Four rubber pads
  • Front and back covers

The company provides an OpenMediaVault image and all instructions on the Wiki. NanoPi NEO 2 board would be much better for such NAS kit, but the low profile Ethernet jack requires a different side cover, and the company also told me the software is not ready, but a NanoPi NEO 2 NAS kit is coming later this month. Talking about performance, FriendlyELEC gave me a comparison table showing USB to SATA performance for NanoPi NEO (512MB), Raspberry Pi 3 board, and Synology DS916+ NAS.

The USB to SATA speed is actually pretty much as expected considered data is going through a USB 2.0 interface, and somewhat comparable to the values I get doing USB storage tests on Android TV boxes. We can also see the performance on Raspberry Pi 3 is about the same as with NanoPi NEO + NAS Dock, but ovbiously not matching actual NAS with a native SATA interface. Nevertheless, all this does not matter that, as once the 32 MB/s get down to the Fast Ethernet port it has to drop to around 10 MB/s, which is why NanoPi NEO 2 will be a better choice.

Tkaiser of Armbian community also had a look at the hardware and software, and one complain was the lack of UASP support on Jmicron JM20329 chip which would  yield slightly better performance, and the OpenMediaVault image relies on Linux 3.4.39 which lacks many security updates (the latest available version is 3.4.113). If you prefer having a recent Linux kernel, it’s always possible to install Armbian, plus whatever NAS software you’d like to use.

Nevertheless, it’s difficult to beat the price as with $12.99 for the NAS board and enclosure, $9.99 for NanoPi NEO 512MB RAM, and a few extra dollars for shipping you get a complete NAS solution with limited performance, but that should still work as well as current Raspberry Pi NAS solutions on the market. Just add a micro SD card with the operating systems of your choice, a 2.5″ hard drive or SSD, and a 12V/2A power supply, and you’re done.

Open Source ARM Compute Library Released with NEON and OpenCL Accelerated Functions for Computer Vision, Machine Learning

April 3rd, 2017 9 comments

GPU compute promises to deliver much better performance compared to CPU compute for application such a computer vision and machine learning, but the problem is that many developers may not have the right skills or time to leverage APIs such as OpenCL. So ARM decided to write their own ARM Compute library and has now released it under an MIT license.

The functions found in the library include:

  • Basic arithmetic, mathematical, and binary operator functions
  • Color manipulation (conversion, channel extraction, and more)
  • Convolution filters (Sobel, Gaussian, and more)
  • Canny Edge, Harris corners, optical flow, and more
  • Pyramids (such as Laplacians)
  • HOG (Histogram of Oriented Gradients)
  • SVM (Support Vector Machines)
  • H/SGEMM (Half and Single precision General Matrix Multiply)
  • Convolutional Neural Networks building blocks (Activation, Convolution, Fully connected, Locally connected, Normalization, Pooling, Soft-max)

The library works on Linux, Android or bare metal on armv7a (32bit) or arm64-v8a (64bit) architecture, and makes use of  NEON, OpenCL, or  NEON + OpenCL. You’ll need an OpenCL capable GPU, so all Mali-4xx GPUs won’t be fully supported, and you need an SoC with Mali-T6xx, T-7xx, T-8xx, or G71 GPU to make use of the library, except for NEON only functions.

In order to showcase their new library, ARM compared its performance to OpenCV library on Huawei Mate 9 smartphone with HiSilicon Kirin 960 processor with an ARM Mali G71MP8  GPU.

ARM Compute Library vs OpenCV, single-threaded, CPU (NEON)

Even with some NEON acceleration in OpenCV, Convolutions and SGEMM functions are around 15 times faster with the ARM Compute library. Note that ARM selected a hardware platform with one of their best GPU, so while it should still be faster on other OpenCL capable ARM GPUs the difference will be lower, but should still be significantly, i.e. several times faster.

ARM Compute Library vs OpenCV, single-threaded, CPU (NEON)

The performance boost in other function is not quite as impressive, but the compute library is still 2x to 4x faster than OpenCV.

While the open source release was just about three weeks ago, the ARM Compute library has already been utilized by several embedded, consumer and mobile silicon vendors and OEMs better it was open sourced, for applications such as 360-degree camera panoramic stitching, computational camera, virtual and augmented reality, segmentation of images, feature detection and extraction, image processing, tracking, stereo and depth calculation, and several machine learning based algorithms.

Orange Pi 2G-IoT ARM Linux Development Board with 2G/GSM Support is Up for Sale for $9.90

March 30th, 2017 57 comments

Orange Pi 2G-IoT was unveiled at the start of the year as an ultra cheap ($10) Linux development board with 2G cellular connectivity. The board has just launched for $9.90 + shipping on Aliexpress.

Orange Pi 2G-IoT specifications have changed a little since the initial announced as WiFi is confirmed to be supported:

  • SoC – RDA Micro 8810PL ARM Cortex A5 processor @ up to 1.0 GHz with 2Gbit (256 MB) on-chip LPDDR2 RAM, 4Gbit (512 MB) on-chip SLC NAND flash , 256KB L2 cache, Vivante GC860 3D GPU, and GSM/GPRS/EDGE Modem (Download datasheet)
  • External Storage – micro SD slot
  • Display I/F – LCD connector up to qHD resolution
  • Video – Decoding up to 1080p30, encoding up to 1080p30 H.264
  • Audio I/F – 3.5mm audio +FM jack, built-in microphone?
  • Connectivity – WiFi 802.11 b/g/n + Bluetooth 2.1/EDR module (RDA5991), and 2G GSM/GPRS/EDGE module with SIM card slot
  • Camera – MIPI CSI-2 connector for camera sensor up to 2MP
  • USB – 1x USB host port, 1x micro USB OTG port
  • Expansion – 40-pin GPIO header with SPI, I2C, ADC, GPIOs, PWM, etc…
  • Debugging – 3x pin UART for serial console
  • Misc – 8 selection jumpers, power button, boot selection header
  • Power Supply – 5V via micro USB port; optional battery
  • Dimensions – 68 x 42 mm
  • Certifications – CE and FCC (if we can believe the markings on the PCB silkscreen)

Linaro showcased Ubuntu on the similar Orange Pi i96 board at Linaro Connect Budapest 2017 last month, but I have not been able to find an image, nor source code yet. Needless to say, beginners better wait before buying this board, as everything is new, and software support is unclear at this stage. You’ll also have to check 2G sunset status in your countries, as some have stopped supporting 2G already, while others plan on keeping 2G networks for many more years.

Thanks to OvCa77 for the tip.
