DSP56371 Overview
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
2.2
The DSP56371 uses the DSP56300 core, a high-performance, single clock cycle per instruction engine that
provides up to twice the performance of Motorola's popular DSP56000 core family while retaining code
compatibility with it.
