remote procedure call over a serial link, DMA controller for bulk transfer

Main RDRAM memory bus.

3.2 GB/s

Graphics interface (GIF), DMA channel that connects the EE CPU to the GS co-processor. To draw something to the screen, one must send render commands to the GS via the GIF channel: 64-bit, 150 MHz bus, maximum theoretical bandwidth of 1.2 GB/s.[6]

"SPU1+SPU2" (SPU1 is actually the CPU clocked at 8 MHz and SPU2 is PS1 SPU) Dolby Digital 5.1, DTS 5.1

2 proprietary PlayStation controller ports (250 kHz clock for PS1 and 500 kHz for PS2 controllers) 2 proprietary Memory Card slots using MagicGate encryption (250 kHz for PS1 cards. Up to 2 MHz for PS2 cards with an average sequential read/write speed of 130 kbit/s) 2 USB 1.1 ports with an OHCI-compatible controller AV Multi Out (Composite video, S-Video, RGBS (SCART), RGsB (VGA connector†), YPBPR (component), and D-Terminal) RFU DC Out

Display lists generated by CPU/VPU0 and VPU1 are sent to the GIF, which prioritizes them before dispatching them to the Graphics Synthesizer for rendering.
