In this paper, we outline the criteria that should be considered when selecting a processor for a signal processing application. We then present a methodology for evaluating processor performance on signal processing applications based on BDTI’s well-known signal processing benchmarks. Unlike processor vendors’ benchmarks, the BDTI Benchmarks™ are independent and objective, ensuring fair comparisons. In addition, the BDTI Benchmarks are designed to minimize the impact of varying programmer skill, ensuring true measurement of processor performance. We explain the limitations of the BDTI Benchmarks and the careful analysis required to apply results to a specific application.
