Automatic code generation for integrated digital signal processors

Novel algorithms for optimizing compilers are discussed which automatically generate efficient instruction code for integrated digital signal processors. Since these processors are primarily used in real-time applications for digital signal processing, the code has to meet high quality requirements. In general, conventional compiler design techniques do not lead to satisfactory results because signal processors and microprocessors are very different in architecture. The algorithms for automatic code generation presented use a very general description of the target machine. They can be applied to a large number of modern integrated digital signal processors. As an example, results of a compiler based on these algorithms generating code for the integrated digital signal processor DSP56000 are presented
