A Retargetable Compiler of VLIW ASIP for Media Signal Processing

Abstract * In the last decade extensive researches have been carried out in ASIP (Application Specific Instruction Processor) design field. One of the key steps in ASIP design is code generation by a retargetable compiler. In this paper we describe our experience in implementing a retargetable compiler for VLIW ASIP based on ORC (Open Research Compiler) framework. Orienting towards a new register file access architecture model, we narrate the process making modifications on ORC framework to get the compiler. The experimental results indicate that our method is effective to get compilers retargeting at VLIW ASIPs
