GPUs Comparison: ARM Mali vs Vivante GCxxx vs PowerVR SGX vs Nvidia Geforce ULP

I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge. There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. [Update: Two comments mentioned Qualcomm Adreno and Broadcom VideoCore are missing from the list. Maybe I’ll do an update later]. Each company offers many different versions and flavors of their GPU as summarized below. ARM Imagination Technologies Vivante Nvidia Mali-400 Series: Mali-400 MP Mali-450 MP Mali-600 Series Mali-T604 Mali-T624 Mali-T628 Mali-T658 Mali-T678 PowerVR SGX Series 5: SGX520 SGX530 SGX531 SGX535 SGX540 SGX545 PowerVR SGX Series 5XT: SGX543MP1-16 SGX544MP1-16 SGX554MP1-16 PowerVR SGX Series 6: G6200 G6230 G6400 G6430 G6600 2D graphics: GC300 GC350 3D graphics: GC400 GC800 GC1000 GC2000 GC4000 ULP GeForce (Tegra […]

Ambarella Unveils A9 4K Ultra HD Camera SoC

Ambarella has recently today introduced the A9 camera System on Chip (SoC) with support for the new 4K Ultra HD video standard in order to power next generation of mirrorless, sports, and digital still cameras. Ambarella A9 SoC features two ARM Cortex A9 cores (surprisingly), as well as Ambarella Image and Video DSPs. The A9’s video features include video timelapse modes, capture of high-resolution still images during video recording, Electronic Image Stabilization (EIS), and burst capture of up to sixty 12-megapixel still images per second. Ultra-wide angle and small form factor lenses are supported with full lens distortion correction. The A9 also support High Dynamic Range (HDR) video. Ambarella A9 Feature Summary: 4K Ultra HD video recording @ 30 fps. High definition video recording at 720p @ 240fps and 1080p @ 120fps. Burst mode support for still image capture of over 700 Megapixels per second. Multi-exposure High Dynamic Range (HDR) […]

Modular Graphics on Embedded ARM – ELCE 2012

Philipp Zabel, kernel developer at Pengutronix, discusses about graphics and video support for Linux on embedded SoCs at Embedded Linux Conference Europe 2012. Abstract: Porting Linux to new ARM based application processors has recently become easier than ever: the kernel gained many new frameworks like common-clock, oftree and pinmux. However, things get complicated when it comes to high end embedded graphics units.Those graphics systems tend to be composed of a multitude of on-SoC functional blocks that can operate on shared graphics buffers and video signals, as well as off-SoC encoder/converter chips that can be mixed and matched with any SoC.The old framebuffer is certainly not enough for today’s hardware any more, while modern frameworks like KMS and DRM have their own hassles on non-PC style graphics systems.The talk outlines issues we found while working on graphics and video support for the MX53 and MX6 CPUs and gives suggestions for possible […]

Inside Android’s User Interface – ELCE 2012

Karim Yaghmour, Opersys inc, talks about the internals of the Android user interface at Embedded Linux Conference Europe on November 5, 2012. Abstract: Android is a very complex stack comprising several dozens of novel components and moving parts. Still, it’s intrinsically a user-centric system and, therefore, its parts which deal with user interface are of special interest for anyone aiming to put Android in a device. This talk will examine the internals of Android’s user-facing components. Specifically, we will cover the inner-workings and interactions of the Window Manager, Surface Flinger, Input Method Manager, and the rest of the system. We will also cover key display and input components such as the Status Bar, Soft Keyboard and Notifications. This talk will be especially useful to developers intending to use Android in user-facing embedded systems, those needing to implement support for their graphics hardware and anyone interested in the internals of Android’s […]

Etnaviv Project Vivante GCxxx GPU Open Source Driver

You have most probably heard of Lima, an initiative to provide fully open source Mali-200 & Mali-400 drivers by reverse-engineering the closed source Mali GPU drivers. A separate effort, Etnaviv Project, has now started to offer open source drivers for Vivante GCxxx GPU used in SoC such as Marvell Armada 1500 (notably used in mainly Google TV platforms), Rockchip RK2918 (present in many older tablets), Freescale i.MX6 (used in newer tablets, low cost development boards, some SoMs and GK802/Hi802 mini PCs). The project is called Etnaviv. The introduction of Etnaviv Project reads as follows on the corresponding Github account: Project Etnaviv is an attempt to make an open source user-space driver for the Vivante GCxxx series of embedded GPUs. The current state of the project is experimental. It is currently only of use to developers interested in helping develop open source drivers for the hardware, reverse engineering, or in interfacing […]

QNX CAR 2.0 Demo and Texas Instruments OMAP5 Jacinto 6 Processor

There’s a Bentley GT concept car at CES 2012 to demonstrate QNX CAR 2.0 platform that provides dual screen support with the dashboard and an infotainment display for the automotive industry. Under the hood, the platform features TI DLP technology, and TI OMAP5 and Jacinto processors running QNX Neutrino RTOS. Texas Instruments and QNX uploaded a video demo of the concept on YouTube. They explain that they switched their platform from HTML5 to native OpenGL for optimal performance using Storyboard Suite from Crank software, and they can now show 3D maps smoothly on the platform. The 1080p user display is curved to be more user friendly (better touch angles). You must have certainly heard about touchscreens before, but maybe never heard about “pretouch”. Pretouch is a feature of the system that detect when you hand comes close to a control virtual and pops up a virtual menu. The dashboard shows […]

Piglit OpenGL Driver Testing Framework Now Works with ARM Linux & OpenGL ES

Piglit is a collection of automated tests for OpenGL implementations that aims at improving the quality of open source OpenGL drivers by providing developers with a simple means to perform regression tests. ARM SoCs that come with a GPU usually (always?) supports OpenGL ES however. That’s why, Tom Gall (Linaro) has modified Piglit in order to bring this test suite to ARM Linux and OpenGL ES. There are about 6,900 OpenGL tests in Piglit, and currently 1,047 Piglit (OpenGL ES) tests can run on ARM . Tom also explains that piglit developers are now using waffle, a cross-platform C library that allows one to defer selection of GL API and window system until runtime. This will allow your to select the variation of the GL API (GL, GL ES) and windowing system (X11, Wayland…) you want to use at runtime. The code is still heavily modified, but it’s in the […]
