What are the key features of Transaction Elimination?
Transaction Elimination (TE) is a bandwidth saving feature of the Arm Mali Midgard and Bifrost GPU architectures which allows for significant energy savings on a System on Chip (SoC) level. When performing TE, the GPU compares the current frame buffer with the previously rendered frame and performs a partial update only to the particular parts of the frame that have been modified, thus significantly reducing the amount of data that needs to be transmitted per frame to external memory.
Some of the key features of TE are:
- No impact to image quality
- Agnostic of frame buffer format
- Per tile comparison between frame buffers
- 16×16 pixels tile size
- CRC-based signature comparison
