The basic operators try to resemble - assembly language instructions that are commonly found in - digital signal processor (DSP) CPUs, thus allowing algorithm - C-code implementations more directly mapeable to DSP assembly - code. - - ********************************************************* - NOTE: so far, this module does not have a demo program! - ********************************************************* - -FUNCTIONS: - Defined in basop.h.
