General Information
Useful information about the Power Architecture and computer architecture in general:
• Programming Environments Manual for 32-Bit Implementations of the PowerPC™ Architecture
(MPCFPE32B)
• Using Microprocessors and Microcomputers: The Motorola Family, William C. Wray, Ross
Bannatyne, Joseph D. Greenfield
• Computer Architecture: A Quantitative Approach, Second Edition, by John L. Hennessy and David
A. Patterson.
• Computer Organization and Design: The Hardware/Software Interface, Second Edition, David A.
Patterson and John L. Hennessy.
Power Architecture Documentation
Power Architecture documentation is available from the sources listed on the back cover of this manual,
as well as our web site, http://www.freescale.com/powerpc.
• Reference manuals (formerly called user’s manuals)—These books provide details about
individual Power Architecture implementations and are intended to be used in conjunction with the
PowerPC Programmers Reference Manual.
• Addenda/errata to reference manuals—Because some processors have follow-on parts, an
addendum is provided that describes the additional features and functionality changes. Also, if
mistakes are found within a reference manual, an errata document will be issued before the next
published release of the reference manual. These addenda/errata are intended for use with the
corresponding reference manuals.
• Data sheets—Data sheets provide specific information regarding pin-out diagrams, bus timing,
signal behavior, and AC, DC, and thermal characteristics, as well as other design considerations.
• Product briefs—Each device has a product brief that provides an overview of its features. This
document is roughly equivalent to the overview (Chapter 1) of a device’s reference manual.
• Application notes—These short documents address specific design issues useful to programmers
and engineers working with Freescale Semiconductor processors.
Additional literature is published as new processors become available. For a current list of Power
Architecture documentation, refer to http://www.freescale.com/powerpc.
Conventions
This document uses the following notational conventions:
cleared/set
When a bit takes the value 0, it is said to be cleared; when it takes a value of 1, it
is said to be set.
