Mali-DP500 Series Display Processor

The ARM® Mali-DP500 offers an extensive range of functionality, including composition, rotation and scaling, within a very small die area. By processing tasks offloaded from the GPU and through its support for ARM Frame Buffer Compression (AFBC) it is able to considerably lower system-wide power consumption. With compatibility for ARM TrustZone® technology.

Building on the feature set of the ARM® Mali-DP500, the Mali-DP550 display processor offers enhanced capabilities for offloading tasks such as composition, scaling, rotation and image post-processing from the GPU in order to save power. Within a very small silicon area and at low energy consumption, the Mali-DP550 adds support for up to seven display layer composition and includes energy efficient technologies such as AFBC. In addition, its co-processor interface enables third parties to incorporate their own display IP in the Mali-DP550 display pipeline.
