Processor pair brings immersive content to mobiles

Two processors are designed to deliver more immersive and interactive visual content on mobile devices. The Mali-V61 video processing unit (VPU) provides real-time 4K 120 video performance; the Mali-G51 graphics processing unit (GPU) is the company’s most area-efficient, and energy-efficient GPU to date. The Vulkan-enabled GPU extends new Bifrost architecture to mainstream devices, says the company.

The Mali-V61 delivers 4K live streaming for real-time video applications such as Facebook Live and Periscope. There is a 50 per cent bit-rate saving over previous generation codecs to enable efficient transmission of high definition content. The VPU also scales from 1080p60 on a single core, up to 4K120 on multiple cores, for what the company claims is the highest definition streaming on any mobile device, from premium through mainstream to entry level.

VP9 encode is soon expected to be a requirement in Android and Google apps, therefore its inclusion enables the ecosystem to future-proof silicon and devices. The VPU is the only multi-standard codec featuring high quality HEVC and VP9 encode in a single scalable IP block.

Based on ARM’s Bifrost architecture, which has been updated to include a redesigned texturing unit with double the throughput, the Mali-G51 GPU enables low power VR such as virtual spaces, superior everyday gaming, AR and fast browsing, bringing premium graphics to mainstream mobile devices, according to the company.

It is the company’s smallest and most efficient Vulkan-enabled GPU for screen resolutions up to 4K. The processor delivers up to 60 per cent more performance per mm² and is up to 60 per cent more energy-efficient than its predecessor, the Mali-T830 GPU. Mali-G51 is also 30 per cent smaller, reducing manufacturing cost.

Both the Mali-V61 VPU and the Mali-G51GPU are designed to seamlessly interact as part of the Mali Multimedia Suite and ARM Cortex-A processors. The former includes graphics, video and display processors for simpler integration and faster time to market for partners.

Both processors are available to license now and both support ARM initiatives such as the new version, v1.2, of ARM Frame Buffer Compression (AFBC), for bandwidth savings, and ARM TrustZone security technology.
