The growth of Software Defined Radio SDR using general purpose processors GPPs brings a new engineering decision of processor selection to radio design. In this study we are concerned with comparing the performance of an SDR toolkit called GNU Radio on different processors. Properly selecting a processor for a radio application will depend on the application however, a generic list of benchmarks would include Floating Point OPerations per second FLOPs for common routines on multiple-processors time to complete common mathtype conversions system latency Knowledge of an application could then be paired with benchmark comparisons of potential processors to make an informed decision on the best processor for size, weight, power or cost constrained applications.
