As shown in Figure 1-3, the keys to DSP are as follows:

•

The Multiply/Accumulate (MAC) operation

•

Fetching operands for the MAC

•

Program control to provide versatile operation

•

Input/Output to move data in and out of the DSP

MAC is the basic operation used in DSP. The DSP56K family of processors has a dual
Harvard architecture optimized for MAC operations. Figure 1-3 shows how the DSP56K
