The T622 is a dual-core GPU and part of ARM's second generation of Mali
T6XX GPUs that offers a 50 percent improvement over other T6XX GPUs by
way of an implementation of Adaptive Scalable Texture Compression
(ATSC). This a lossy block-based system for the compression and
decompression of textures used in graphics rendering on the fly. The
energy efficiency is achieved by minimizing the amount of memory used to
ATSC was developed at ARM but has been donated
to the industry and adopted as a official extension for both OpenGL and
OpenGL ES by the Khronos Group.
The T622 supports OpenGL ES 3.0,
Google's Renderscript Compute and OpenCL 1.1 full profile making the
smallest GPU core able to support general purpose computing, according
to Jakub Lamik, product manager in ARM's media processing division.
also provide software development kit routines and libraries under
OpenCL where we can support use cases for GPGPU. With the pair of cores
including the CPU, ARM's SIMD [single instruction multiple data] engine
NEON and the dual-cored GPU the company is looking work its way towards
heterogeneous computing. "It's about running the right task on the right
core – or even about running the right part of task on the right core,"
said Rosinger. The GPGPU use cases being supported include vision
stablization, gesture and facial recognition," said Lamik.
premium feature set of the Cortex-A12 processor will enable new use
cases previously only limited to high-end devices and will allow the
mid-range mobile device segment to continue growing rapidly," said
Tzu-Mu Lin, senior vice president, at Via Technologies Inc. (Taipei,
Taiwan), in statement issued by ARM.
