Chapter 10. The Diamond 570T Superscalar CPU Core

Superscalar processors are the natural next step in the evolution of general-purpose processors.

—Mike Johnson

Superscalar Microprocessor Design

The Diamond 570T CPU core is a high-performance, 3-way static-superscalar RISC CPU core. The term superscalar describes a processor that achieves superlative performance by executing multiple scalar instructions per clock cycle. Just as warp engines allow the Starship Enterprise to break the speed-of-light barrier, superscalar execution pipelines allow the Diamond 570T CPU to break the 1-instruction-per-clock barrier that limits conventional scalar RISC architectures. Scalar instructions are the instructions found in the ISAs of most general-purpose ...
