Turnip is an Open Source Vulkan Driver for Adreno GPU

Qualcomm Adreno GPUs have one of the best open source GPU driver for Arm SoC thanks to Freedreno driver. The driver relies on OpenGL ES API however, and nearly four of years ago, Khronos introduced the Vulkan API that aims to reduce CPU resources usage, and adds support multiple command buffers. The good news is there has been development of a Vulkan driver for Adreno 500 and 600 series GPU called Turnip, also referred to as Freedreno_vk (Freedreno Vulkan) in the code. The Turnip driver has been developed by Bas Nieuwenhuizen, a Site Reliability Engineer at Google who also happens to be RADV (Radeon Vulkan) lead developer, Chia-I Wu, a Google software engineer working on Android graphics, Chad Versace, Intel’s software engineer working on Linux OpenGL stack, and others as revealed by a recent merge into Mesa 19.1 slated to be released next quarter.

Qualcomm Unveils Snapdragon 210 LTE SoC for Entry-Level Smartphones

Android smartphones with LTE connectivity are now available for a little over $100, for example with LANDVO L200G powered by Mediatek MT6582 with an external MT6290 LTE modem, but prices may soon even get lower, as Qualcomm has now unveiled their latest Snapdragon 210 processor with integrated LTE modem to bring sub $100 LTE smartphones to market in 2015. For once, they’ve even provided detailed technical specifications for their new mobile application processor: Processor – Quad ARM Cortex A7 up to 1.1GHz GPU – Adreno 304 GPU with OpenGL ES 3.0, OpenCL, DirectX, content security, and decreased power consumption DSP – QDSP6 DSP Memory/Storage – LPDDR2/LPDDR3@533MHz, eMMC 4.5, and SD 3.0 (UHS-I) Display – Up to 720p, with external displays supported Modem Integrated 4G LTE-Advanced World Mode, supporting LTE FDD, LTE TDD, WCDMA (3C-HSDPA, DC-HSUPA), CDMA1x, EV-DO Rev. B, TD-SCDMA and GSM/EDGE 4G LTE CAT4 speeds of up to 150 […]

Qualcomm Announces SnapDragon S4 MSM8226 & MSM8626 Quad Core Cortex A7 Processors

After news of an AllWinner A31 Tablet earlier today, here’s an other quad core Cortex A7 processor announcement, as Qualcomm has recently added of 2 new chipsets to its Snapdragon S4 family of mobile processors: the MSM8226 and MSM8626 featuring 4 ARM Cortex A7 core and Adreno 305 GPU. The processors support 1080p video playback and up to 13MP cameras. Both processors are built using 28nm technology node, and will be ready for customer sampling by Q2 2013 for UMTS, CDMA and TD-SCDMA. These 2 chipsets will incorporate WTR2605, a new multi-mode radio transceiver, specifically designed and optimized to address China requirements such as support for TD-SCDMA, CDMA 1xAdv and HSPA+. The WTR2605 transceiver comes with an integrated, high-performance GPS core with GLONASS and Beidou support, and is said to offer 40 percent power savings and 60 percent smaller footprint compared to previous generations. The company will also provide Qualcomm […]

Qualcomm Showcases Quad Core Snapdragon APQ8064 Application Processor

Way back in February 2011, Qualcomm announced the Snapdragon APQ8064, a quad core application processor clocked at up to 2.5 GHz, that was (and still is) supposed to be available in products end of 2012, beginning of 2013. They now have samples, and showcased the processor in an Android tablet reference design at UpLink 2012. The APQ8064 is part of SnapDragon S4 Pro family and features 4 Krait cores running at up to 1.5 GHz when all four cores are running, or up to 1.7 GHz when only one core is active, according to Anandtech. So it appears they did not follow up on the 2.5 GHz promise. APQ8064 is the first SoC featuring Adreno 320 GPU, and will be followed by MSM8960 later on. The demo below shows the 3D performance of the Qualcomm processor and GPU, and Raj Talluri, Senior Vice President, Product Management at Qualcomm, claims the […]
