Integrating Custom Instruction Specifications into C Development Processes

摘要

We describe a new approach for creating hardware description language (HDL) specifications for custom instructions, to form part of the instruction-set architecture (ISA) of an application specific instruction set processor (ASIP). Our approach integrates fully into the traditional C development process, binding tightly with software source code and simplifying the ASIP optimisation process. Our tool is also free software, facilitating its use in future research.
