Retargetable Generation of Code Selectors from HDL Processor Models
Rainer Leupers, Peter Marwedel · 1997
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 speci ed processor models. In contrast to previous work, our retargetable compiler Record does not requiretoolspeci c 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-o between processor architectures and program execution speed. 1
