Abstract
Application Specific Instruction Set Processors (ASIPs) have become popular in the development of embedded systems. For these processors easily-retargetable, high-performance compilers play a key role in the development process, improving productivity and reducing time-to-market. We propose a novel, object-based architecture description language (ADL) OpenDL, as well as a well-structured Rule Library to automatically retarget compiler backends. OpenDL is a succinct and high-quality ADL with object-based inheritance features, while the Rule Library applies instruction templating in order to allow detailed instruction specification to handle complex rule patterns. We use these tools to automatically retarget the open source industrial-strength compiler Open64 to the high-performance embedded processor PowerPC. A reliable version of auto-retargetable industrial-strength compiler is generated which achieves comparable performance to gcc 4.5 for both the EEMBC and SPEC CPU 2000 benchmarks.
