PowerPC Processor Core
The MPC8240 contains an embedded version of the PowerPC 603e™ processor called the
processor core. This chapter provides an overview of the basic functionality of the
processor core. For detailed information regarding the processor refer to the following:
•
MPC603e & EC603e User’s Manual (those chapters that describe the programming
model, cache model, memory management model, exception model, and instruction
timing)
•
MPC603e & EC603e Microprocessor User’s Manual Errata (those sections that
pertain to the programming model, cache model, memory management model,
exception model, and instruction timing)
•
PowerPC™ Microprocessor Family: The Programming Environments for 32-Bit
Microprocessors
This section describes the details of the processor core, provides a block diagram showing
the major functional units, and describes briefly how those units interact. At the end of this
chapter, there is a section that outlines the detailed differences between the processor core
and the MPC8240 processor.
5.1 Overview
The processor core is a low-power implementation of the PowerPC microprocessor family
of reduced instruction set computing (RISC) microprocessors. The processor core
implements the 32-bit portion of the PowerPC architecture, which supports 32-bit effective
addresses.
