ARM Cortex A15/A17 SoCs Comparison – Nvidia Tegra K1 vs Samsung Exynos 5422 vs Rockchip RK3288 vs AllWinner A80

We’re now starting to get quite a few players with ARM Cortex A15 cores on the market, as well as some with ARM Cortex A17. So a comparison table of different quad and octa SoCs might be a useful thing to do. I’ve put aside SoCs such as HiSilicon K3V3, and OMAP5, and focused on the four latest processors: Nvidia Tegra K1 (32-bit), Samsung Exynos 5422, Rockchip RK3288 and AllWinner A80. I haven’t included Mediatek MT6595 and Qualcomm SnapDragon 805, because the two companies mainly focus on smartphones and tablets (although it appears to be slowly changing for Qualcomm), documentation is usually difficult or impossible to find, and in the case of Qualcomm they use their own ARMv7 Krait cores. I’ve highlighted some features in green, in case a particular SoC appears to have an edge. Rockchip RK3288 AllWinner A80 Nvidia Tegra K1 Samsung Exynos 5422 CPU 4x ARM Cortex-A17 […]

Linaro 14.04 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.04 has been released with Linux Kernel 3.14 (baseline), Linux Kernel 3.10.37 (LSK), and Android 4.4.2. More work has been done on ARMv8 support, and big.LITTLE for both the Linux kernel and Android, as well as work on member hardware platforms such as Origen, Arndale, Arndale Octa, Broadcom Capri, and Hisilicon D01 boards. GCC 4.8-2014.04 Linaro is said to include performance improvements. Linaro Android engineering builds for Nexus 7 and Nexus 10 have been setup, but I can’t quite find the images. They’ve also added the BeagleBone Black to member builds. Here are the highlights of this release: Linaro Stable Kernel (LSK) 3.10.37-2014.04 Updates to Android support (from Google and Linaro) Added Big endian for ARMv7 and ARMv8 Thermal framework DT support Huge pages and transparent huge pages for ARMv8 Tagged pointers for ARMv8 Non-coherent DMA for ARMv8 Other Features big.LITTLE support – ARM MP patch set, IKS (ARMv7 […]

Samsung Gear 2 Smartwatches are Powered by Exynos 3250 SoC

When Samsung announced their Gear 2 and Gear 2 Neo smartwatches running Tizen, they only vaguely mentioned a dual core processor running at 1 GHz powered the devices. SamMobile reports the two watches should be powered by a new processor called Exynos 3250 with two cores and clocked at 1 GHz as initially announced. Ifixit also made a tear down of the Gear 2 watch, and at first, it seems Exynos 3250 is nowhere to be seen, but it turns out it’s probably combined with a DRAM (and Flash?) package named KMF5X0005M, and shown inside a red square in the picture above. Samsung Galaxy Gear, the company’s first smartwatch, was a modified version of Exynos 4212 dual core processor, but using only one core and downclocked to 800 MHz. SamMobile thinks the Gear 2 can use a dual core processor @ 1 GHz, due to battery life gains achieved by […]

OpenCL Accelerated SQL Database with ARM Mali GPU Compute Capabilities

We’ve previously seen GPU compute on ARM could improve performance for mobile, automotive and consumer electronics application. GPU compute offload CPU task that can be parallelized to the GPU using APIs such as OpenCL or RenderScript. Most applications that can leverage GPU compute are related to media processing (video decoding, picture processing, audio decoding, image reconigion, etc…), but one thing I did not suspect could be improve is database access. That’s what Tom Gall, Linaro, has achieved in a side project by using OpenCL to accelerate SQLite database operations by around 4 times for a given benchmark. The hardware used was a Samsung Chromebook with an Exynos 5250 SoC featurig a dual core Cortex A15 processor and an ARM Mali T604 GPU. CPU compute is only possible on ARM Mali T6xx and greater, and won’t work on Mali 400 / 450 GPUs. Other GPU vendors such as Vivante and Imagination […]
