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
