Integrating Custom Instruction Specifications into C Development Processes

Abstract

Translate Article

Abstract 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.KeywordsClock CycleIntegrate Development EnvironmentBenchmark ProgramManual ImplementationCustom UnitThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
