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.

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
