24-Bit Audio Digital

Signal Processor

Motorola designed the DSP56362 to support digital audio applications requiring digital audio compression

and decompression, sound field processing, acoustic equalization, and other digital audio algorithms. The

DSP56362 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 DSP56362 offers 100 million instructions per second (MIPS) using an internal

100 MHz clock at 3.3 V.
