Signal Processor
Freescale Semiconductor, Inc.
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.
