Mali-D51 Display Processor

Arm-MALI-D51 Block Diagram.

About Mali-D51

Arm Mali-D51 is the first Display Processor to bring the benefits of the new Komeda Display architecture to the Mainstream. Mali-D51 offloads the GPU by performing composition, in-line rotation, high quality scaling gamma/de-gamma and other imaging processing before sending the final image to the screen.

Key features

  • 8 Composition layers, Scaling split operation
  • 8 AFBC rotation layers, Encoding of uncompressed layers to AFBC1.2 for efficient rotation
  • Mixed HDR/SDR composition
  • MMU optimizations such as integrated TBU and tight-coupling of MMU-600

Key display solution benefits

  • Achieves twice the scene complexity within the same area of Mali-DP650
  • 50% better memory latency when coupled with MMU-600 
  • Seamlessly integrates with Assertive Display 5 for an optimal HDR experience even on a standard display
