The GPU used in PS Vita is a PowerVR SGX543MP4+.

Kernel module SceGpuEs4 is very similar to the Linux PVR kernel module which is open source. A lot of versions are available, see for example


  • EDM: Event Data Master
  • PDS: Program Data Sequencer
  • PVR: PowerVR
  • TA: Tile Accelerator
  • USSE: Universal Scalable Shader Engine


Memory context

The GPU has its own MMU. Every render context (one per application) gets its own GPU virtual address space. The MMU tables are managed by the ARM kernel. When a user calls sceGxmMapMemory the kernel first checks if the memory's accessible by the user and then maps it to the GPU with the same virtual address. However there are also other memory areas mapped to the GPU:
