DSP Run-Time Library Guide

DSP Run-Time Library Guide
The DSP run-time library contains functions that you can call from your
source program. This section describes how to use the library and provides
information on the following topics:

Calling DSP Library Functions
To use a DSP library function, call the function by name and give the
appropriate arguments. The names and arguments for each function are
described in the function's reference page in the section
Library Reference" on page
Like other functions you use, library functions should be declared. Decla-
rations are supplied in header files, as described in the section,
With Library Header Files" on page
The function names are C function names. If you call C run-time
library functions from an assembly language program, you must
use the assembly version of the function name, which is the func-
tion name prefixed with an underscore. For more information on
naming conventions, see the section,
guage Interface" on page
You can use the archiver, described in the VisualDSP++ 3.5 Linker
and Utilities Manual for 16-Bit Processors, to build library archive
files of your own functions.
