Software Development on the High-Speed Systolic Array Processor (HISSAP): LessonsLearned

摘要

This report documents the lessons learned in programming the Naval Ocean SystemCenter's (NOSC's) High-Speed Systolic Array Processor (HISSAP) testbed. The procedures used for code generation, along with the programming utilities provided in the software development environment, are discussed with regard to their impact on the efficient implementation of algorithms on a parallel processing system such as HISSAP. This information is intended for considerations pertaining to software-development environments in future Navy parallel processing systems. Many of HISSAP's software-development utilities played key roles in the implementation of two computationally intensive algorithms: the Multiple-Signal Classification algorithm (MUSIC) and a four-channel, narrowband, finite-impulse response (FIR) filter. The introduction of utilities not included with the HISSAP tools would undoubtedly have increased the speed and efficiency of software development.
