DSP56366 24-Bit Digital Signal Processor User Manual, Rev. 4
Freescale Semiconductor i
Preface
This manual describes the DSP56366 24-bit digital signal processor (DSP), its memory, operating modes,
and peripheral modules. The DSP56366 is a member of the DSP56300 family of programmable CMOS
DSPs. Changes in core functionality specific to the DSP56366 are also described in this manual.
The DSP56366 is targeted to applications that require digital audio compression and decompression,
sound field processing, acoustic equalization, and other digital audio algorithms.
This manual is intended to be used with the following publications:
• The
DSP56300 Family Manual (DSP56300FM),
which describes the CPU, core programming models,
and instruction set details.
• The
DSP56366 Technical Data Sheet (DSP56366)
, which provides electrical specifications, timing,
pinout, and packaging descriptions of the DSP56366.
These documents, as well as Freescale’s DSP development tools, can be obtained through a local Freescale
Semiconductor Sales Office or authorized distributor.
