Architecture
The MPC823e microprocessor uses a dual-processor architecture design approach with large data
and instruction caches to provide high-performance using a general-purpose RISC integer
processor and a special-purpose 32-bit scalar RISC communication processor module. The
peripherals are uniquely designed for communication requirements and can provide embedded
signal processing functions for communication and user interface enhancements and the I/O
support needed for high-speed digital communication.
The MPC823e is comprised of four main modules that interface with the 32-bit internal bus:
The embedded PowerPC core
The system interface unit
The communication processor module
LCD controller
