Evaluating DSP Processor Performance

Digital signal processing (DSP) is the application of mathematical operations to digitally represented signals. Because digital signals can be processed with cost-effective digital integrated circuits, DSP systems can economically accomplish complex tasks, such as speech synthesis and recognition, that would be difficult or impossible to accomplish using conventional analog techniques.

The market for products using DSP technology, such as wireless communication devices and digital audio appliances, is growing rapidly. Semiconductor manufacturers have responded to this demand by producing an expanding array of DSP processors—microprocessors designed specifically for digital signal processing. Selecting the right DSP processor for an application is a difficult and time-consuming task for DSP system designers. This paper presents a methodology for evaluating DSP processor performance, one of the key considerations in choosing a processor.
