Multiprocessor scheduling for high quality digital audio

The paper describes investigations into multiprocessor scheduling techniques for high quality audio DSP. A DSP processor/multiprocessor simulator is introduced which allows register-level simulation of multiprocessor DSP architectures and parallel DSP algorithms. The simulator has been used to investigate the implementation of recursive filtering algorithms for audio, using multiprocessor DSP architectures. Results from these studies are presented and discussed. Also described are multiprocessor DSP algorithm mapping and scheduling techniques based on genetic algorithms. These investigate techniques using genetic algorithms to schedule audio DSP algorithms written in the form of data flow graphs onto specified DSP multiprocessor arrays. The basic techniques are described and initial results from these studies are also presented and discussed
