2025年3月1日 · The N64 Reality Signal Processor (RSP) is the part of the Reality Co-Processor (RCP) that deals with data transform. It is a MIPS-based cpu like the main R4300 cpu but it also contains additional 8-bit vector opcodes.
N64 Programming Manual - Ultra) 64
This document describes the graphics state machine of the RCP, with a particular focus on the RSP (please see Section 3.3, "RSP: Reality Signal Processor”). The RSP is an R4000-like CPU with an 8-element vector unit, featuring a small instruction memory, IMEM (4K bytes or 1K instructions) and small data memory, DMEM (4K bytes).

2018年11月24日 · The CPU controls the RCP through DMA (to transfer the code) and SP_STATUS (to start and stop it), and communicates with the CPU through the RSP's COP0 instructions. The RCP controls essentially all peripheral access on the Nintendo 64 which includes, but is not limited to: video, audio and serial.
N64 Introductory Manual - Ultra) 64
The RCP has two processors (RSP and RDP) and I/O interfaces (VI, AI, PI, and SI). The RCP is the most important component of the N64 hardware system as shown in the following illustration. All data passes through the RCP, and the RCP serves as a memory controller for the CPU.
