Chapter 6. Automated Processor Configuration and Instruction Extension

David Goodwin, Steve Leibson, and Grant Martin

The idea of an ASIP—application-specific instruction-set processor—is central to every chapter in the book. Nevertheless, we will briefly review the ASIP concept to put the idea of automated processor configuration into context.

General-purpose processors are exactly that: processors that implement a relatively generic instruction set applicable to a wide variety of applications that cannot be easily predicted in advance or that are of a diverse nature. The trend in general-purpose microprocessor design over the last three decades has been to create faster and faster processors with deeper pipelines (to achieve high clock rates) ...
