| PS2 (GS+EE) | |||
|---|---|---|---|
| Core | Job | Source | Notes |
| SPU0 | Spu2 | SPU Assembly | Spu2 emulator |
| SPU1 | Sif | SPU Assembly | Some kind of bridge to IOP, since SIF is part of EE hardware. |
| SPU2 | Timer | SPU Assembly | IOP timers. |
| SPU3-6 | - | - | Unknown, emulator seems to not use them |
| SPU7 | - | - | Unavailable: Factory disabled SPU |
| PPU:0 | PS2-Devices | C++ and PPU ASM | |
| PPU:1 | IOP | PPU ASM | Interpreter, dmas, iop hw regs, etc. |
| PS2-EE | Emotion Engine | Hardware CXD2953AGB | Only in CECHAxx and CECHBxx PS3 models with COK-001 motherboard |
| PS2-GS | Graphic Synthesizer | ||
| PS2_GX | |||
| Core | Job | Source | Notes |
| SPU0 | IOP | SPU ASM | I/O Processor (originally PS1 main processor) |
| SPU1 | PS2-SPU2 | SPU ASM | Sound processing unit 2 |
| SPU2 | IPU | SPU ASM | Image Processing Unit |
| SPU3 | VU1 | SPU ASM | Vector Unit 1 |
| SPU4 | EEDMA | SPU ASM | EE DMA plus VIF1 handler |
| SPU5 | GSGIF | SPU ASM | GIF (GS Interface, very limited since GS is on board) |
| SPU6 | ? | ? | Emulator never access it directly but can be possibly used for MagicGate. Emulator sends/receives MG data thru virtual uart port 10. |
| SPU7 | - | - | Unavailable: Factory disabled SPU |
| PPU:0 | PS2-Devices | C++ and PPU ASM | |
| PPU:1 | Emotion Engine | C++ and PPU ASM | |
| PS2-GS | Graphic Synthesizer | Hardware CXD2972GB | Only in CECHCxx PS3 models with COK-002 motherboard |

| Core | Job | Source | Notes |
| SPU0 | IOP | SPU ASM | I/O Processor (originally PS1 main processor) |
| SPU1 | SPU2 | SPU ASM | Sound processing unit 2 (originally SPU from PS1) |
| SPU2 | VU1 | SPU ASM | Running VU1 code translated previously on PPU side. |
| SPU3 | EEDMA | SPU ASM | Partial DMAC, mostly channels 1/2, and VU1 CODE r/w. Also process VIF1 commands (incl. Unpacks). |
| SPU4 | FE | SPU ASM | GIF unit, processing GIF tags, handling GS internal registers, etc. |
| SPU5 | BE | SPU ASM | |
| SPU6 | IPU | SPU ASM | EE Image Processing Unit |
| SPU7 | BE | PPU/SPU ASM | Factory disabled SPU. Emulator set name for JOB, but never try to start/set it as active. Although a lot of code in emulator is ready to use it. |
