ABSTRACT:
This invention describes a numeric intensive real-time software development system for programming low cost fixed point digital signal processors (DSP's) and other programmable devices in which code efficiency, ease of programming and code portability are maintained. DSP's being a generic math engine are proliferating into many areas, far beyond the traditional filtering applications. Numeric intensive is the most distinctive nature of the DSP software, and one of the biggest challenges in DSP software development is to implement complicated math algorithms in low cost fixed-point DSP's. The software development system describes an approach where low level assembly language is enhanced with high level syntax and further augmented with an enhance numeric handler for converting between numeric formats. Debug of the DSP programs is aided by the numeric format conversion and the use of high level syntax. The resulting program is written to a driver interface which facilitates porting code between different DSP's.
