Mali Display Processors
The Mali display roadmap 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.The Mali-DP650 is the latest product on the display roadmap and offers additional features over the Mali-DP550, such as it is optimized for 2.5k formats including WQXGA (2560x1600 pixels) for tablets and WQHD (2560x1440) for a mobile screen.
With compatibility for ARM TrustZone® technology, the Mali display technologies secure the display path for use cases such as mobile payment and video playback. Crucially, when a Mali display processor is implemented in a complete ARM-based SoC, the Android driver for each processor will, by design, work together extremely efficiently; this highly optimized multimedia software significantly reduces implementation effort while at the same time delivering best in class performance and maximized power efficiency.
As resolutions and display quality increase, display processing becomes even more important in a media system. Having a dedicated display processor that not only controls output to the screen but also enables the GPU to offload basic tasks such as multi-layer composition or image post-processing to a dedicated processor improves visual quality and reduces overall SoC power consumption. ARM® Mali™ Display Processors are designed with three key benefits in mind: lowering system bandwidth, simplifying software integration and offering a secure display path.
