Ansi C Math Library Functions Supported By The Dsk Assembler - Texas Instruments TMS320C3 Series User Manual

Expression Analyzer
5.5 Expression Analyzer
The expression analyzer used in the DSK assembler includes ANSI C math
library functions that aid in the generation of tables and constants. These func-
tions eliminate the tedious work of calculating tables and constants before in-
cluding them in the assembly process. The functions are shown in Table 5–2.
Note:
If you use any of these functions, a post-assembly warning is generated to
remind you that these functions are not supported by the TMS320 floating-
point code generation COFF tools. If you want to use these functions with the
COFF toolset, then extract the resulting hexadecimal values from the DSK
listing file.
