Advance Information
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.
