A brief history of the development of dedicated single-chip Digital Signal Processing (DSP) devices is followed by an examination of the features of DSP devices which differentiate them from general-purpose microprocessors. It is shown how these features make them particularly suitable for DSP algorithms. Various choices confront the designer of a DSP-based system. Fundamental to these is the choice of system architecture, which naturally includes the choice of a specific device to perform the signal processing function. This paper attempts to help this choice, not by comparing and contrasting available devices, but by examining the implications of this choice of architecture for the performance of the system as a whole.
