Wave Computing to Open Source MIPS Architecture

There has been a lot of talks about RISC-V open source, royalty-free instructions set architecture this year, including the launch of RISC-V MCUs and Linux capable RISC-V processors, and corresponding development boards such as Hifive Unleashed. This even lead Arm to create a – now shutdown – microsite telling why people should stick with Arm instead of RISC-V. While RISC-V was clearly on the rise this year, MIPS architecture once a dominant players in routers and set-top box has been on the decline, even prompting Blu to write a guest review entitled “Baikal T1 MIPS Processor – The Last of the Mohicans?” hinting at the near extincsion of MIPS based solutions. But there may be hope, or at least a last ditch effort, with Wave Computing purchasing MIPS from Imagination Technology earlier this year, and now announcing the MIPS Open Initiative to effectively open source 32-bit and 64-bit MIPS ISA […]

BOOM Open Source RISC-V Core Runs on Amazon EC2 F1 Instances

The Berkeley Out-of-Order Machine (BOOM) is an open source RV64G RISC-V core written in the Chisel hardware construction language, and mainly ASIC optimized. However, it is also usable on FPGAs, and developers support the FireSim flow to run BOOM at over 90 MHz on Xilinx Ultrascale+ FPGAs found in Amazon EC2 F1 instances. The BOOM core was created at the University of California, Berkeley in the Berkeley Architecture Research group, in order to create a high performance, synthesizable, and parameterizable core for architecture research. Key features of BOOM core: ISA – RISC-V (RV64G) Synthesizable FPGA support Parameterized Floating Point (IEEE 754-2008) Atomic Memory Op Support Caches & Virtual Memory Boots Linux Privileged Arch v1.11 External Debug BOOM is said to be inspired by the MIPS R10k and the Alpha 21264 out–of–order processors, based on a unified physical register file design (aka as “explicit register renaming”). The source code for the […]

Necuno Mobile Open Source Linux Smartphone is Powered by NXP i.MX 6 Processor

A few years ago, various companies tried to develop other Linux based mobile operating systems, but most failed with Mozilla Firefox OS discontinued, Samsung Tizen is not being used in smartphones anymore, and Sailfish OS giving up the consumer market focusing on governmental and corporate customers instead. There’s still a niche market however for privacy-focused, open source Linux smartphones, and we’ve already covered NXP i.MX 8M based Purism Librem 5 smartphone scheduled to launch next year with GNOME based PureOS operating system, and the ability to switch to PureOS with KDE Plasma Mobile or Ubuntu Touch. Necuno Mobile will be another Linux smartphone based on an NXP processor, but instead of relying on a 64-bit i.MX 8M processor, it will be equipped with the older 32-bit i.MX 6Quad processor, and according to the company be “100% open source device, from metal to pixel, from hardware to software”. Necuno Mobile preliminary […]

Open Source Hardware SpiderSoM System-on-Module Features Intel MAX 10 FPGA

When embedded systems companies offer a system-on-module (SoM) and a baseboard, the later is usually open source hardware with all design files provided so that customers can leverage the work for their own baseboard, but files for the SoM are normally not released to customers. Intel MAX 10 FPGA based Aries SpiderSoM and SpiderBase change that, as the company has decided to release both the module and carrier board KiCAD designs under a CERN OHL v1.2 license. SpiderSoM system-on-module specifications: FPGA – Intel MAX 10 FPGA in F256 package from 10M04DC to 10M50DA System Memory – Optional 128/256/512MB DDR3 DRAM for 10M 16/25/40/50 FPGAs Storage – Optional 4 MB SPI NOR, optional 4 GB eMMC flash 230-pin MxM2 edge connector with 178x FPGA GPIO pins, including 13 LVDS transmitters and 54 receivers Misc – RTC with battery backup, programmable clock generator and PLL, with optional external reference input Power Supply […]

Silicon Labs Releases Z-Wave Public SDK, Raspberry Pi 3 Image

Z-Wave is a wireless communication protocol initially developed by Zensys, before being purchased by Sigma Designs which provided Z-Wave compliant chips, and this year Silicon Labs purchased Z-Wave from Sigma Designs, Z-Wave is fairly popular in the US, and the Z-Wave alliance has certified around 2,400 products so far. However, we seldom hear about hobbyist projects featuring Z-Wave because the wireless protocol is proprietary, documentation was not available publicly, and you’d also need a few thousands dollars to get started: $4,000 a year to be a Z-Wave Alliance member, $2,500 for certification, and the development kit sells for about $2,000… But in 2016, things improved with Sigma Designs releasing Z-Wave Application Layer specifications publicly, as well as Z-Wave over IP (Z/IP), Z-Ware Middleware, and the Z-Wave S2 Security Specification. But you still needed to acquire the Z-Wave SDK and obtain access to the Z-Wave Technical Support website and the Z-Wave […]

Dav1d Open Source AV1 Decoder Aims to be Fast and Lightweight

Lots of efforts are being put into AV1 open source, royalty-free video codec with the AV1 specification published in March, and companies like YouTube and Netflix having recently uploaded AV1 video samples for testing and evaluation. We also reported FFmpeg 4.0 was released with AV1 supporting using libaom reference decoder. However, the library is not really optimized for code size and speed, but instead just to demonstrate AV1 decoding and encoding. So VideoLAN, VLC and FFmpeg communities have been working on another decoder called Dav1d – which stands for “Dav1d is an AV1 Decoder” – that aims to be lightweight, cross-platform, fast and open source. Some of the technical details about dAV1d include: written in C99 without VLAs (Variable Length Arrays) ASM in NASM/GAS syntax (no intrinsics), Meson/ninja buildsystem, Works on x86, x64, ARMv7, ARMv8 architectures for now Runs on Windows, Linux, macOS, Android, iOS operating systems Licensed under BSD […]

Realtek RTD1296 U-boot & Linux Source Code Released, RTD1619 Cortex A55 SoC Shows up in Code

Media centers based on Realtek RTD1295 or RTD1296 processors have been around for a few years. They usually run both Android and OpenWrt operating systems for respectively media functions (4K video playback, HDMI input recording…), and NAS functions like file sharing. media downloads, etc…. SinoVoIP also unveiled Banana Pi BPI-W2 board powered by RTD1296 last year, but so far I was not aware of any source code for the target. Synlogy actually released a Linux 4.4 tarball a while ago, but more recently SinoVoIP released Linux 4.9.119 and U-boot source code for RTD1296 in Github. You’ll find instructions to build from source, and flash the resulting U-boot and Kernel image from the Github page. There’s also some mainline Linux support for RTD1295, but maybe this release will help further speed up mainline support. Beside code for RTD129x (RTD1295/RTD1296), we’ll find references to RTD139x (RTD1395) a cost-down version of RTD1295, as […]
