A-1 Overview The DSP56364 supports digital audio applications requiring sound field processing, acoustic equalization, and other digital audio algorithms. The DSP56364 uses the high performance, single-clock-per-cycle DSP56300 core family of programmable CMOS digital signal processors (DSPs) combined with the audio signal processing capability of the Motorola Symphony™ DSP family, as shown in Figure 1. This design provides a two-fold performance increase over Motorola’s popular Symphony family of DSPs while retaining code compatibility. Significant architectural enhancements include a barrel shifter, 24-bit addressing, instruction cache, and direct memory access (DMA). The DSP56364 offers 100 million instructions per second (MIPS) using an internal 100 MHz clock at 3.3 V.
