ARM unveils new graphics core Mali-T658

Scalable up to eight cores, works with the ARM Cortex-A15 and Cortex-A7 processors

By CBR Staff Writer

ARM has unveiled its Mali-T658 graphics processing unit (GPU) based on the Midgard architecture for high performance devices, such as superphones, tablets and smart-TVs.

The company claims that Mali-T658 GPU delivers up to ten times the graphics performance of the Mali-400 MP GPU and four times the GPU compute performance of the Mali-T604 GPU.

The Mali-T658 GPU is supported by ARM Partners, such as Fujitsu Semiconductor, LG Electronics, Nufront and Samsung.

The Mali-T658 is scalable up to eight cores, and number of arithmetic pipelines can be double within each of these cores, as well as compatible with the ARMv8 architecture.

The new platform supports a wide range of graphics and compute APIs, including Google Renderscript, Khronos OpenGL ES, Khronos OpenCL, OpenVG, Microsoft DirectX 11, and Microsoft DirectCompute.

According to the company, the Mali-T658 works seamlessly with the ARM Cortex-A15 and Cortex-A7 processors either in standalone modes or in big.LITTLE processing mode, and features cache coherency to maintain the consistency of data stored in local caches of a shared resource.

ARM Media Processing Division general manager Pete Hutton said next generation consumer devices based on the Mali-T658 GPU will address the growing user expectation for slick user interfaces and desktop-class graphics.
