Glossary

DOS/4GW: A memory extender that is bound with the DOS version of the TMS470R1x code generation tools. The executable DOS/4GW file is not shipped separately but is embedded within the other executables. Error messages from DOS/4GW are included in Appendix A, Troubleshooting DOS Systems, to assist you in debugging. If you receive one of these error messages, contact technical support for assistance, and remember that the tools are shipped as object files with the memory extender embedded.

DOS/16M: The executable filename for a tool that is embedded in the TMS470R1x code generation tools. You may occasionally see this term in an error message. If so, see Appendix A, Troubleshooting DOS Systems, for the appropriate action.

E

environment variables: System symbols that you define and assign to a string. They are usually included in batch files (for example, .cshrc).

I

interlist utility: A compiler utility that inserts as comments your original C source statements into the assembly language output from the assem- bler. The C statements are inserted next to the equivalent assembly instructions.

L

linker: A software program that combines object files to form an object mod- ule that can be allocated into system memory and executed by the de- vice.

lnk470: The name of the command that invokes the linker for the TMS470R1x.

O

optimizer: A software tool that improves the execution speed and reduces the size of C programs.

options: Command parameters that allow you to request additional or specific functions when you invoke a software tool.
