Practical Applications and Benchmarks of GPU Computing via RenderScript and OpenCL with ARM Mali-T6XX GPU

Since the announcement of ARM Mali-T604 in 2010, ARM has explained that GPGPU (General Purpose computing on GPU), aka GPU Compute, would be one of the key features of their new Mali graphics processor, and the company now expects GPGPU to become mainstream in embedded and mobile devices in 2014 and beyond. I’ve just come across a presentation by Roberto Mijat, technical marketing manager at ARM, entitled “Unleashing the benefits of GPU Computing with ARM Mali” which shows practical applications and use cases where the use of RenderScript, or OpenCL can make massive performance improvements, at much lower power consumption, over the same parallel tasks processed by the CPU only. Let’s have a look at some of the most interesting slides. GPU compute can be used for multiple applications in mobile, multimedia, and automotive sectors. GPU Compute for H.265 / HEVC HEVC aka H.265 is the next generation codec providing […]

Linux Kernel 3.12 Released

Linus Torvalds has announced the release of Linux Kernel 3.12: I was vacillating whether to do an rc8 or just cut the final 3.12, but since the biggest reason to *not* do a final release was not so much the state of the code, as simply the fact that I’ll be traveling with very bad internet connection next week, I didn’t really want to delay the release. Sure, we had a number of driver reverts, and there was an annoying auto-NUMA memory corruption fix series, but none of it was really worth delaying 3.12 for. But the fact that I’m going to be (effectively) off-line next week means that I’m *not* opening the merge window for 3.13 yet – since I won’t have the bandwidth to really do merges anyway. That doesn’t mean that you can’t send me pull request for the merge window early, of course – maintainers can […]

ARM Unveils Mali-T720 and Mali-T760 GPUs

ARM has recently announced two new Mali GPUs: Mali-T760 for high-end smartphones and tablets, and Mali-T720 for entry-level devices, but with better performance and energy performance compared to previous cost-optimized Mali GPUs, as well as OpenGL ES 3.0 support. These new GPUs have already been licensed by companies such as MediaTek, Rockchip, Samsung and LG Electronics.   Mali-T760 GPU ARM lists the key benefits and features of the ARM Mali-T760 GPU as follows: An increase in energy efficiency and performance of approximately 400 percent over the ARM       Mali-T604 GPU; Scaling to 16 shader cores, which doubles the previous generation, plus an increase in both performance per shader core and overall performance; Reduction of internal and SoC bandwidth utilization, significantly reducing energy consumption, enabled by ARM Frame Buffer Compression (AFBC), and Smart Composition, delivering more than 50 percent reduction in total memory bandwidth utilization; Simplified implementation through reduced wire count and […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into  Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

Rockchip SoCs Comparison Table, RK32xx Quad Core Cortex A12 Coming Up in 2014

They guys at Linux Rockchip have setup a comparison table between Rockchip processors, but it’s not quite complete yet, and Rockchip noticed it, so they’ve just sent them the most recent Company Presentation that provides more details, including a roadmap. In this documentation, we can see the company targets different types of products with their SoCs: Android OTT dongle/box (aka mini PC, HDMI TV dongles…) – RK2928, RK3066, RK3068, and RK3188 Tablets – RK2926, RK2928, RK3028, RK3066, RK3168, and RK3188 EPD E-Book – RK2818, RK2906 and RK2918 MP3 player – RKnanoC On page 12 of the presentation, they have a convenient comparison table for the SoC used in mini PCs and Tablets.

Vivante GC4000 is The Best Mobile GPU… When It Comes to Accuracy

Most of the time, mobile GPU comparisons involve benchmarks such as Antutu, Nenamark 2, etc…, or people may consider which games will be able to run smoothly with a particular device, but we seldom compare image quality, for the simple reason it’s usually more difficult to achieve. YOUi Labs has just done that, however, by running the shader code below on several hardware platforms, mainly Android tablets, with the most common mobile GPUs, and used the results obtained with a  Desktop PC GPU, Nvidia Geforce GT 630M, has a reference.

Here are the results: The worst GPUs are Mali-400 MP4 in Exynos 4412 and Geforce ULP in Tegra 3, which can respectively only show 5 and 8 lines before degradation, and the top two GPUs are Qualcomm Adreno 225 in MSM8660A, and Vivante GC4000 in HiSilicon K3V2 processor. Imagination Technologies SGX544 and ARM Mali-T604 also provide decent results, but […]
