Audience
This manual is intended for system software and hardware developers and applications
programmers who want to develop products using the 603e microprocessors. It is assumed
that the reader understands operating systems, microprocessor system design, the basic
principles of RISC processing, and details of the PowerPC architecture.
Organization
Following is a summary and a brief description of the major sections of this manual:
Chapter 1, “Overview,” is useful for readers who want a general understanding of
the features and functions of the PowerPC architecture and the 603e. This chapter
describes the flexible nature of the PowerPC architecture definition, and provides an
overview of how the PowerPC architecture defines the register set, operand
conventions, addressing modes, instruction set, cache model, exception model, and
memory management model.
Chapter 2, “Programming Model,” provides a brief synopsis of the registers
implemented in the 603e, operand conventions, an overview of the PowerPC
addressing modes, and a list of the instructions implemented by the 603e.
Instructions are organized by function.
Chapter 3, “Instruction and Data Cache Operation,” provides a discussion of the
cache and memory model as implemented on the 603e.
Chapter 4, “Exceptions,” describes the exception model defined in the PowerPC
OEA and the specific exception model implemented on the 603e.
Chapter 5, “Memory Management,” describes the 603e’s implementation of the
memory management unit specifications provided by the PowerPC OEA for
PowerPC processors.
Chapter 6, “Instruction Timing,” provides information about latencies, interlocks,
special situations, and various conditions to help make programming more efficient.
This chapter is of special interest to software engineers and system designers.
Chapter 7, “Signal Descriptions,” provides descriptions of individual signals of the
603e.
Chapter 8, “System Interface Operation,” describes signal timings for various
operations. It also provides information for interfacing to the 603e.
Chapter 9, “Power Management,” provides information about power saving modes
for the 603e.
