ARM IP addresses demand for richer mobile VR and 4K streaming

New Products |

The two new products are designed to address “Generation Z” and mainstream demands for more immersive and interactive visual content on mobile devices. The Mali-V61 video processing unit (VPU) promises stunning, real-time 4K120 video performance with impressive efficiency and scalability; while the Mali-G51 graphics processing unit (GPU) is ARM’s most area-efficient and energy-efficient GPU to date.

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

Inclusion of VP9 encode in the Mali-V61 enables the ecosystem to future-proof silicon and devices, as VP9 encode is soon expected to be a requirement in Android and Google apps. The Mali-V61 VPU is, ARM says, the only multi-standard codec featuring high quality HEVC and VP9 encode in a single scalable IP block.

Introducing the Mali-G51, ARM notes that consumers purchasing mainstream smartphones expect enhanced functionality and access to features including low power VR such as virtual spaces, superior everyday gaming, AR and fast browsing. Based on ARM’s new Bifrost architecture which has been updated to include a redesigned texturing unit with double the throughput, the Mali-G51 GPU enables these use cases, bringing premium graphics to mainstream mobile devices.

Mali-G51 is ARM’s smallest and most efficient Vulkan-enabled GPU for screen resolutions up to 4K. The processor delivers up to 60% more performance per mm² and is up to 60% more energy-efficient than its predecessor, the Mali-T830 GPU. Mali-G51 is also 30% smaller, reducing the cost of manufacturing high-volume chips while enabling it to address more high-performance use cases.

Both the Mali-V61 VPU and the Mali-G51GPU are designed to seamlessly interact as part of the wider Mali Multimedia Suite and ARM Cortex-A processors. Both processors support ARM initiatives such as the new version, v1.2, of ARM Frame Buffer Compression (AFBC), to deliver increased bandwidth savings, and ARM TrustZone technology to enable a secure foundation for consumer products.
