The MPC8260 contains an embedded version of the PowerPC 603eª processor. 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 UserÕs Manual (Those chapters that describe the
programming model, cache model, memory management model, exception model,
and instruction timing)
¥ PowerPCª 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 brießy how those units interact.
The signals associated with the processor core are described individually in Chapter 7, Ò60x
Signals.Ó Chapter 8, ÒThe 60x Bus,Ó describes how those signals interact.
2.1 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.
Figure 2-1 is a block diagram of the processor core.
