About This Manual

The TMS470R1x Code Generation Tools Getting Started Guide tells you how to install release 1.20 of the TMS470R1x code generation tools on your sys- tem. It also provides the following information:

-Tells you how to set environment variables for parameters that you use often

-Gets you started using the compiler, linker, and assembler

-Provides a list of the media contents for your tools set, so you will know what information is associated with each file you have installed

-Details enhancements in this release and tells you where to find further information

-Describes how you can resolve problems that you may encounter on a PCrunning DOS (MS-DOSor PC-DOS)

Notational Conventions

In this document, the following notational conventions are used:

-Program listings, program examples, and interactive displays are shown in a special typeface. Examples use a bold version of the spe- cial typeface for emphasis. Interactive displays use bold to distinguish commands that you enter from items that the system displays (such as prompts, command output, error messages, etc.). Some interactive displays use italics to describe the type of information that should be entered.

Here is a sample program listing:
