This library is embedded in the FrameDll.lib contains a collection of useful functions for developing custom audio modules. At a minimum, each function is implemented in C to provide functionality on the PC and baseline performance on embedded processors. In some cases, functions have been optimized in assembly for specific processors.
The functions provided fall into 3 broad categories:
Fractional math library — code which emulates fractional arithmetic on the PC. This is used to first develop Blackfin modules on the PC. See FractMath.h.
Filter design library — filter design and coefficient calculation routines for basic filter types. In floating-point or double precision. See FilterDesign.h
Math helper library — floating-point versions of the math library. Used on the PC. See MathHelper.h.
Refer to the individual header files for a description of each function and its arguments.
