R4400 Microprocessor User's Manual


3. The CPU Pipeline


This chapter describes the basic operation of the CPU pipeline, which includes descriptions of the delay instructions (instructions that follow a branch or load instruction in the pipeline), interruptions to the pipeline flow caused by interlocks and exceptions, and R4400 implementation of an uncached store buffer.

The FPU pipeline is described in Chapter 6.
