DSP56374 Data Sheet
1 Overview
The DSP56374 is a high-density CMOS device with
3.3 V inputs and outputs.
NOTE
This document contains information on a
new product. Specifications and
information herein are subject to change
without notice.
For software or simulation models (for
example, IBIS files), contact sales or go

The DSP56374 supports digital audio applications
requiring sound field processing, acoustic equalization,
and other digital audio algorithms. The DSP56374 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 Semiconductor,
Inc. Symphony™ DSP family, as shown in Figure 1.
Significant architectural enhancements include a barrel
shifter, 24-bit addressing, and direct memory access
