Overview

Slave to the CPU

The RSP operates as a slave to the CPU. As such, there are limited error
recovery facilities and many features are explicitly managed at a low level
(booting, IMEM, DMEM, etc.)

Part of the RCP

Figure 2-1, reproduced from the
illustrates the major functional blocks of the RCP.
The RSP, along with the RDP and the IO subsystem, comprise the RCP chip.
The RSP and RDP operate independently and are connected with the XBUS.
The IO block of the RCP also includes memory interfaces and separate DMA
engines for the RSP and RDP.
