Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

AllWinner Linux-sunxi Community Presentation and Status Report – FOSDEM 2014

Oliver Schinagl, a member of linux-sunxi community working on open source kernel and bootloader for AllWinner SoCs, has given a presentation of the community at FOSDEM 2014 to give an overview, and show what progress has been made to date. I’ll write a summary in this post, but if you want to watch the video and/or access the slides scroll down at the bottom of the post. After explaining what sunxi is, and introducing himself, he gave some information about AllWinner and their SoCs: Founded in 2007 in Zhuhai, Chiang now with 550 employees including 450+ engineers 15% market share in 2013 for tablet SoCs, only behind Apple. Products: F-series SoC (2010), A10 (2011), A13, A10s (2012), and A20 (2013). (cnsoft He skipped A31(s) and A80 here as they are not really supported by the community). They list “Open Source Source” and “GPLv3” in their marketing materials although they clearly […]

DragonBox Pyra Open Source Handheld Game Console To Feature TI OMAP5432 SoC.. or AllWinner A80, or Intel Bay Trail, or Qualcomm Snapdragon…

Pandora is an open source handheld console which development started as far back as 2007. The project has had ups and downs, and some people have yet to receive the device they pre-ordered. As many components are now more difficult to source, Pandora has reach end-of-life, as Pandora 2 is now being developed with a subset of the original team, but has been renamed to DragonBox Pyra to start afresh. The new version aims to take to the good aspects of the original Pandora, and improve on the bad ones, so that DragonBox will have a faster hardware with a better looking case and better control. Here are the specifications listed on the project website: SoC – Texas Instruments OMAP 5432 SoC with 2x ARM Cortex-A15 @ 1.7Ghz with NEON SIMD, 2x ARM Cortex-M4, Imagination Technologies PowerVR SGX544-MP2 GPU for 3D graphic, and Vivante GC320 GPU for 2D graphics System […]

Cute Embedded Nonsense Hacks, Nouveau Driver for Tegra K1, and Android Defaults to ART

There’s been some news at the end of this week that may not warrant a full article, but are still fun and/or interesting nonetheless: comments by the lead developer of Fedora ARM led to “Cute Embedded Nonsense” meme on Google+, preliminary commit for open source drivers for Tegra K1’s GPU, and Android Open Source Project defaults to ART instead of Dalvik. If you have a Google+ account, and circled a few people involved in ARM Linux, you must have seen a few postings about “Cute Embedded Nonsense Hacks” in your feed. It all started when Jon Masters posted about Red Hat’s ARM SBSA platform requirements, and in particular one comment that reads: I am all for people installing their own kernels if they want to. I support aggressively defined standard platforms (not cute embedded nonsense hacks) but not locked platforms. You can keep both parts when it breaks, of course. […]

The Open Source Robots Invasion Has Begun: BeagleMiP, uARM, and PiddyBot

In the last few days, I’ve come across three affordable open source robots either based on BeagleBone Black, or Arduino compatible boards, and I’m sure there are many other projects out there for people interested in getting started with robotics without breaking the bank. BeagleMiP Self-balancing Robot I’ve found out the first robots from a long armdevices.net video showing two Mobile Inverted Pendulum (MiP) robots, able to stand on two wheels, designed by the Coordinated Robotics Lab of The University of California, San Diego: BeagleMiP educational robotics development kit from Strawson Design. The kit features the BeagleBone Black board with Texas Instruments Sitara ARM Cortex A8 processor and Novus Robotics Cape, an add-on board that provides 9-axis IMU (Accelerometer, Gyro, Magnetometer), 6 PWM connectors to power servos or brushless ESCs, 2 user-accessible buttons and 2 LEDs, a cell balancer & overvoltage protector, H-bridges to drive 6 DC Motors, and connectors […]

Telechips TCC893x Dual Core ARM Cortex A9 + Cortex M3 SoCs: TCC8930, TCC8933, TCC8935

Sometimes last year, Telechips discreetly released a triple core SoC comprised of 2 ARM Cortex A9 cores and one Cortex M3 core for tablet, set-top boxes, media player and car AVN (Audio, Video & Navigation). A dual core release in 2013 may not be that interested, but the addition of a Cortex M3, and high performance interfaces such as Gigabit Ethernet and USB 3.0 may make it interesting. Let’s have a look. There’s very little information on Telechips TCC893x page, apart from the block diagram above and the following description: The TCC893x is a system-on-chip with powerful multimedia solution and high performance such as dual decoding. It is ideal for high-end multimedia devices such as Set top box, Media Box, Car AVN, and Tablet. TCC893x multimedia application processor based on Cortex-A9 Dual & M3 has multi-format hardware video accelerator optimized to reduce power consumption, high-performance 2D/3D graphic engine for rich […]
