Audience
Additionally, the MPC7400 implements the AltiVeca technology resources. There are two
books which describe the AltiVec technology:
¥
AltiVec Technology Programming Environments Manual
(AltiVec PEM
)
is used as a
reference guide for programmers. The AltiVec PEM provides a description for each
instruction that includes the instruction format, an individualized legend that
provides such information as the level(s) of the PowerPC architecture in which the
instruction may be found, the privilege level of the instruction, and Tgures to help in
understanding how the instruction works.
AltiVec Technology Programming Interface
(AltiVec PI) is used to provide an
efTcient and expressive mechanism for programmers to access AltiVec technologys
functionality from programming languages such as C and C++. The AltiVec PI
deTnes a programming model for use with the AltiVec instruction set extension to
the PowerPC architecture. There are three types of programming interfaces
described in the document:
¥
The PowerPC Architecture: A SpeciTcation for a New Family of RISC Processors
deTnes
the architecture from the perspective of the three programming environments and remains
the deTning document for the PowerPC architecture. For information about ordering
PowerPC documentation, see òSuggested Reading,ó on page xxxix.

Audience
This manual is intended for system software and hardware developers and applications
programmers who want to develop products for the MPC7400. It is assumed that the reader
understands operating systems, microprocessor system design, 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, òOverview,ó is useful for readers who want a general understanding of
the features and functions of the PowerPC architecture and the MPC7400. This
chapter describes the exible nature of the PowerPC architecture deTnition, and
