The DSP library (libdsp-omf.a) provides a set of digital signal
processing operations to a program targeted for execution on a dsPIC digital signal
controller (DSC). In total, 49 functions are supported by the DSP Library.
Documentation for these libraries is provided in HTML Help files. Examples of
use may also provided. By default, the documentation is found in the
docs\dsp_lib subdirectory of the MPLAB XC16 C Compiler install
directory (see “Libraries Overview, Compiler Installation Locations”).
