Manual Organization - Motorola DSP56303 User Manual

Chapter 1
Overview
This manual describes the DSP56303 24-bit digital signal processor (DSP), its memory,
operating modes, and peripheral modules. The DSP56303 is an implementation of the
DSP56300 core with a unique configuration of on-chip memory, cache, and peripherals.
Use this manual in conjunction with the DSP56300 Family Manual (DSP56300FM/AD),
which describes the CPU, core programming models, and instruction set. The DSP56303
Technical Data (DSP56303/D)—referred to as the data sheet—provides DSP56303 electrical
specifications, timing, pinout, and packaging descriptions.
You can obtain these documents—and the Motorola DSP development tools—through a local
Motorola Semiconductor Sales Office or authorized distributor. To receive the latest
information on this DSP, access the Motorola DSP home page at the address given on the
back cover of this document.
