DSP56371 Overview
2.1 Introduction
This manual describes the DSP56371 24-bit digital signal processor (DSP), its memory,
operating modes and peripheral modules. The DSP56371 is a member of the DSP56300
family of programmable CMOS DSPs. The DSP56371 is targeted to applications that
require digital audio compression/decompression, sound field processing, acoustic
equalization and other digital audio algorithms. Changes in core functionality specific to the
DSP56371 are also described in this manual. See Figure 1. for the block diagram of the
DSP56371.
