Retargetable code generation for application-specific processors

An approach of intelligent retargetable compiler is introduced to overcome the gap between hardware and software development and to increase performance of embedded systems. It focuses on knowledgeable treatment of code generation where knowledge about target microprocessor architecture and human-level heuristics are integrated into compiler expert system. Structure of an experimental compiler supporting code generation for DSPs and VLIW-DSPs is described. A technique to detect optimal instruction set architecture for program execution is presented. Results of code generation experiments are presented for DSPstone benchmarks.
