DSP56371 Audio Processor Architecture
This section defines the DSP56371 audio processor architecture. The audio processor is composed of the
following units:
The DSP56300 core is composed of the Data ALU, Address Generation Unit, Program Controller,
DMA Controller, Memory Module Interface, Peripheral Module Interface and the On-Chip
Emulator (OnCE). The DSP56300 core is described in the document <st-blue>DSP56300 24-Bit
Digital Signal Processor Family Manual, Motorola publication DSP56300FM/AD.
Phased Lock Loop and Clock Generator
Memory modules
Peripheral modules. The peripheral modules are defined in the following sections.
Memory sizes in the block diagram are defaults. Memory may be differently partitioned, according to the
memory mode of the chip. See Section 2.4.7 On-Chip Memory for more details about memory size.
