Appendix B

Glossary

A

asm470: The name of the command that invokes the assembler for the TMS470R1x.

assembler: A software program that creates a machine-language program from a source file that contains assembly language instructions, direc- tives, and macro definitions. The assembler substitutes absolute opera- tion codes for symbolic operation codes and absolute or relocatable addresses for symbolic addresses.

C

C compiler: A software program that translates C source statements into assembly language source statements.

code generator: A compiler tool that takes the file produced by the parser

or the optimizer and produces an assembly language source file.

COFF: Common object file format. A binary object file format that promotes modular programming by supporting the concept of sections. All COFF sections are independently relocatable in memory space; you can place any section into any allocated block of target memory.

cl470: The name of the command that invokes the compiler shell program for the TMS470R1x. (The second character in the shell name is a lower- case L.)

D

DOS/4G: The base version for DOS/4GW. You may occasionally see this term in an error message. If so, see Appendix A, Troubleshooting DOS Systems, for the appropriate action.
