ARM promises richer mobile VR and 4K streaming with new graphics chips

The new processors can support the increasing demand for higher real-time video performance and enhanced user experience.

By CBR Staff Writer

ARM has unveiled two new products namely Mali-V61 video processing unit (VPU) and Mali-G51 graphics processing unit (GPU) to improve 4K 120 video performance and for more immersive and interactive visual content on mobile devices.

The first product Mali-V61 (VPU) has been designed to handle 4K live streaming for real-time video applications including Facebook Live and Periscope.

ARM says that the processing efficiency has been achieved by a 50% saving in bit-rate compared to previous generation codecs to transmit high definition content without any glitches.

The processing unit can scale up 1080p60 on a single core and up to 4K120 on multiple cores, offering highest definition streaming on any mobile device ranging between premium medium and entry levels.

The Mali-V61 VPU comes with VP-9 encode, an open source video-coding format developed by Google.

ARM says that by adding this video encode, it has ensured that mobile devices remain future proof as VP9 encode will be added by Google in the forthcoming Android versions and applications. arm2

ARM says that at present, Mali-V61 is the only product which is capable of handling high quality (High Efficiency Video Coding) HEVC and VP9 encode on to a single scalable IP block.

ARM CPU and media processing groups general manager James McNiven said: “The cost and visual experience a device delivers are key purchasing factors for Generation Z and mainstream mobile users.

“Our latest Mali video and graphics IP suite meets this demand by offering immersive VR, gaming and compliance with real-time video standards. This is a system-level media solution that enables developers to balance performance, efficiency and cost control.”

The next product is Mali-G51 is based on new Bifrost architecture, which has been updated to offer enhanced graphics functionality and superior gaming with low power for prolonged battery life.

It claims that the Mali-G51 has the capability to bring enhanced and high-end graphics on to mainstream mobile devices.

Tencent Games Joint Development Product Centre general manager Shen Li said: “We’re now seeing demand for mainstream devices to cater for not only complex UIs and casual gaming but also low power VR and virtual spaces applications.

“To meet these requirements a mainstream GPU needs a balance of area and energy efficiency, all within the smallest silicon area, in order to reduce costs for this competitive, high-volume segment.”

These two graphics processors are part of a wider Mali Multimedia Suite and ARM Cortex-A processors. The processors Mali-V61 and Mali-G51 are now available for licensing.
