DSP56364
24-Bit Audio Digital Signal Processor
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 Freescale Symphony™ DSP
family, as shown in Figure 1-1. This design provides a
two-fold performance increase over Freescale’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.
