Open ARM GPU Drivers FOSDEM 2013 Video and Call to ARM Management

As I previously wrote, FOSDEM organizers are slowly uploading FOSDEM 2013 videos. One of the most interesting talk “Open ARM GPU Drivers” is now available. I’ve also uploaded it to YouTube (embedded below) to give it more exposure. Luc Verhaegen has also written a recent blog post entitled “Hey ARM!” where he announces the release of the modified source for Quake 3 Arena demo, and asks ARM to join them in making an open source driver. Open ARM GPU Drivers @ FOSDEM2013 This session covers the following key points: Problem – Binary drivers are mainly designed to run in Android, and it’s very difficult to have proper GPU drivers for Linux, and companies are not interested to release open source drivers or even just documentation, as they are not convinced it will benefit them in any way. Legal – This is actually the main issue, as open sourcing existing driver […]

AllWinner A10s Processor Overview

Between the AllWinner A10 and AllWinner A13 processors, there’s now an alternative. AllWinner A10s is based on AllWinner A13 architecture (sun5i), but adds HDMI and Ethernet MAC which makes it suitable for mini PCs and set-top boxes. The first time I heard about this processor was in August with IP878 mini PC, and in October, one reader (Alex) informed me AllWinner had posted more details about his new processor. Here are the key features of this (relatively) new SoC: CPU/GPU – ARM Cortex-A8 Core with 32KB D-Cache/ 32KB I-Cache / 256KB L2 Cache, and Mali-400 VPU HD Video Decoding 1080p@30fps of VP8/6, H.264/H.263, WMV9/VC-1, WMV7/8, MPEG-4/2/1, Xvid codecs HD Video Encoding 1080p@30fps with H.264 codec Video Out – HDMI 1.4 (1080p), Memory Up to 1GB DDR2/DDR3 up to 533MHz (16/32 bits Data Bus) MLC/TLC/SLC/EF-NAND ECC 64-bit Peripherals: USB2.0 OTG, USB2.0 HOST （OHCI/EHCI） SD Card V.3.0, eMMC V.4.2 SPI, TWI and […]

ARM Announces 3 New Midgard GPUs – Mali-T624, Mali-T628 and Mali-T678

ARM announced the second generation of the Mali-T600 Series GPUs targeting tablets, smartphones and smart TVs. Those new GPUs provide up to 50% performance increase over the first generation Midgard GPUs (T-604 & T-658) and include  support for Adaptive Scalable Texture Compression (ASTC), a texture compression technique. The company explains that ASTC significantly optimizes GPU performance and increases battery life in devices. Those 3 new GPUs based on Mali Midgard architecture are named as follows: Mali-T624 – 1 to 4 cores – Market: Smartphones and smart-Tvs Mali-T628 – 5 to 8 cores – Market: Smartphones and smart-Tvs Mali-T678 – Up to 8 cores, 4x the GPU compute performance of Mali-T628 – Market: Tablets As with previous Midgard GPUs, the new GPUs support GPU compute with improves performance and energy-efficiency for math intensive activities, such as: Computational photography – computational methods of enhancing or extending digital photography Multi perspective views – […]
