Mali-G31 High Area Efficiency GPU

MALI-G319 Block Diagram.

About Mali-G31

The Arm Mali-G31 GPU is the first ultra-efficient GPU based on the Bifrost architecture. Bringing the benefits of Bifrost to a whole new tier of device, Mali-G31 builds on the success of the previous ultra efficient products in the Mali-400 Utgard series. With significant energy and area savings compared to the next level of device, plus support for the very latest APIs, Mali-G31 is the GPU of choice for cost constrained devices.

Memory System Virtual Memory Built-in Memory Management Unit (MMU) to support virtual memory.
Scalability 
1 uni-pixel core or dual-pixel core Optimized for high area and energy efficiency to address mainstream device requirements.
Adaptive Scalable Texture Compression
(ASTC)
Low dynamic range (LDR) and high dynamic range (HDR). Supports both 2D and 3D images
ASTC offers a number of advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use.
Arm Frame Buffer Compression (AFBC) Version 1.2
4x4 pixel block size
AFBC is a lossless image compression format that provides random access to pixel data to a 4x4 pixel block granularity. It is employed to reduce memory bandwidth both internally within the GPU and externally throughout the SoC.
Transaction Elimination 16x16 pixel block size Transaction Elimination spots the identical pixel blocks between two consecutive render targets and performs a partial update to the frame buffer with the changed pixel blocks only, which reduces memory bandwidth and thus energy.
Smart Composition 16x16 pixel block size Smart Composition extends the concept of Transaction Elimination to every stage of UI composition. Identical pixel blocks of input surfaces are not read, not processed for composition and not written to final frame buffer.
