Abstract

Besides high code quality, a primary issue in embedded code generation is retargetability of code generators. This paper presents techniques for automatic generation of code selectors from externally specified processor models. In contrast to previous work, our retargetable compiler RECORD does not require tool-specific modelling formalisms, but starts from general HDL processor models. From an HDL model, all processor aspects needed for code generation are automatically derived. As demonstrated by experimental results, short turnaround times for retargeting are achieved, which permits to study the HW/SW trade-off between processor architectures and program execution speed.
