1.2 What is a Superscalar Processor?
Pipeline and Superpipeline Architecture
Previous MIPS processors had linear pipeline architectures; an example of such a linear pipeline is the R4400 superpipeline, shown in Figure 1-2. In the R4400 superpipeline architecture, an instruction is executed each cycle of the pipeline clock (PCycle), or each pipe stage.
