Comparison Between Two Kinds Of Digital Signal Processor

In this paper, we compare abilities of two kinds of digital signal processor ( DSP ), M88764 and DSSP1. At first, we implement FIR digital filter and IIR digital filter in using each processor. Next, we implement a discrete Fourier transform by prime factor algorithm in each processor. The numbers of machine cycles and program steps to implement the algorithm in these processing are compared. Moreover, we make it clear how architecture of DSP is suitable for each digital signal processing.
