The RSP is a programmable co-processor apart of the RCP, and is a fixed-point RISC CPU capable of over half a billion arithmetic operations per second! The RSP also operates as a slave to the main CPU, as such, there are limited error recovery facilities and many features are explicitly managed at a low level (booting, IMEM, DMEM, etc.)

  • RSP's COP0 handles processors communication through DMA RSPCOP0
  • RSP has no COP1 for FPU
  • COP2 is the RSP's Vector Unit

Fuck dis, I'll do eet tomorrow or during the week! :3c :3c :3c :3c :3c :3c
