Imagination PowerVR G6230 is the First GPU To Pass Khronos OpenVX 1.1 Conformance

The Khronos Group is the non-profit consortium group behind open standards and APIs for graphics, media and parallel computation such as OpenGL for 3D graphics, OpenCL for GPGPU, OpenVG for 2D vector graphics, etc… OpenVX is one of their most recent open, royalty-free standard, and targets power optimized acceleration of computer vision applications such as face, body and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more. The first revision of the standard was released in 2014, and the latest OpenVX 1.1 revision was just released in May 2016. We’ve already seen OpenVX 1.1 support in Nvidia Jetson TX1 module & board, but Khronos has a conformance program to test  implementations, and if successful, allow companies to use the logo and name of the API. The version first GPU to pass OpenVX 1.1 conformance is Imagination Technologies PowerVR […]

NXP LPC Microcontrollers Roadmap for 2017 – LPC800 and LPC54000 Series

With the acquisition of Freescale, NXP now has both Kinetis and LPC ARM Cortex M micro-controller families. The company has kept selling both so far, but it’s unclear whether they’ll keep developing new Kinetis MCU family in the future. There’s no such doubt about LPC family with the company having published a 2017 roadmap for ARM Cortex M0+ based LPC 800 series, and ARM Cortex M4 based LPC54000 series. LPC800 series MCUs are promoted as 8-bit MCU alternatives, and three new models are expected next year: LPC84x ARM Cortex M0+ @ 30 MHz with 64KB flash, 8 to 16KB RAM available in QFN and LQFP packages. LPC802 ARM Cortex M0+ @ 15 MHz with 16KB flash, 2KB RAM available in TSSOP packages LPC804 ARM Cortex M0+ @ 15 MHz with 32KB flash, 4KB RAM available in QFN or TSSOP packages There will be new models of the more powerful LPC54000 […]

Review of Mecool BB2 Pro TV Box with DDR4 Memory – Part 1: Specs, Unboxing and Teardown

Mecool BB2 Pro is yet another Amlogic S912 Android 6.0 TV box, but after Eweat R9 Plus, it’s my second TV box with DDR4 memory that should deliver much higher bandwidth compared to DDR3 memory used in most TV boxes. But so far, it’s clear how much performance can be extracted from the system with higher memory bandwidth in actual use,  and that’s exactly what I hope to find out in the second part of the review, but in this post I start by going through the specs, check the box and its accessories, as well as the hardware design. Mecool BB2 Pro specifications Apart from the DDR4 memory, BB2 Pro has pretty common specifications: SoC – Amlogic S912 octo-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3 GPU System Memory – 3 GB DDR4 Storage – 16 GB eMMC flash + micro SD slot up […]

Compress & Decompress Files Faster with lbzip2 multi-threaded version of bzip2

Bzip2 is still one of the most commonly used compression tools in Linux, but it only works with a single thread, and I’ve been made aware that lbzip2 allows multi-threaded bzip2 compressions which should lead to much better performance on multi-core systems. lbzip2 was not installed by default in my Ubuntu 16.04 machine, but it’s easy enough to install:

I have cloned mainline linux repository on my machine, so let’s see how long it takes to compress the directory with bzip2 (one core compression):

9 minutes and 22 seconds. Now let’s repeat the test with lbzip2 using all 8 cores from my AMD FX8350 processor:

2 minutes 32 seconds. Almost 4x times, not bad at all. It’s not 8 times faster because you have to take into account I/Os, and at the beginning the system is scanning the drive, using all 8-core but not all full throttle. […]

ReflowR is a $99 SMT Reflowing Tool for Makers and Students

You can solder SMT components to your custom board by hand, but it would be much faster if you could get a reflow tool instead to “bake” your board after placing the components. ReflowR SMT reflowing tool offers just that in a small and affordable form factor. Some people have tried to use DIY solutions to bake their board, but results may vary. ReflowR has been specifically designed to heat PCB offering constant results. It supports reflow, rework, MSD bake, or rework pre-bake, and follows JEDEC reflow profiles. You can also add a WiFi extension to monitor the tool from your smartphone and set the temperature profile. Two version are available: Smart ReflowR – Compact 600W system for for makers and learners. Large ReflowR – Larger 1200W system for professionals “STEM Inspiration kits” are also offered without a ReflowR kit, but with multiple components, solder paste, a few PCBs, tweezers, […]

YokaTV KB2 Review – Amlogic S912 TV Box with 32 GB Flash

CNXSoft: This is another review by Karl about Amlogic S912 based YokaTV KB2 TV box. Introduction Today we will be looking at Videostrong YokaTV KB2. Below are the specs from Videostrong website. This is my first S912 device so I had high expectation. I have been using it for quite some time now with no major issues. I received approximately 6 OTA updates since I started testing and some welcome updates have come. Build When I receive a box first thing I do is take it apart and check out the inside. I was excited when I found out it had 32 gig of storage. It is not too common. Then when I opened the box I was really happy to see an antenna that wasn’t soldered on. Makes it easy to add a different one. +1 for KB2. Then I noticed the heat sink. It seemed a little small. […]
