DSP56300 Core Description
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.
The DSP56300 core family offers a new level of performance in speed and power, provided by its rich instruction set and low
power dissipation, thus enabling a new generation of wireless, telecommunications and multimedia products. For a description
of the DSP56300 core, see Section 2.4 DSP56300 Core Functional Blocks. Significant architectural enhancements to the
DSP56300 core family include a barrel shifter, 24-bit addressing, an instruction patch module and direct memory access (DMA).
The DSP56300 core family members contain the DSP56300 core and additional modules. The modules are chosen from a library
of standard predesigned elements such as memories and peripherals. New modules may be added to the library to meet
customer specifications. A standard interface between the DSP56300 core and the on-chip memory and peripherals supports a
wide variety of memory and peripheral configurations. Refer to DSP56371 User Manual, Section 3, Memory Configuration.
Core features are described fully in the DSP56300 Family Manual. Pinout, memory and peripheral features are described in this
manual.
