This invention describes a numeric intensive development environment for producing code for various fixed point DSP's and providing a debug capability that assists the user by displaying various data from the DSP in various formats. The DSP code is created in a DSP-C language which is based on low level assembly language tools enhanced with extensive native mathematical representation formats and high level language syntax. This provides the advantage of handling numeric representation in high level language and optimizing the code for speed and compactness in low level language. Once the code is created in DSP-C it can be connected to a DSP through a driver and driver interface. The driver interface allows the code to be universal with a different driver being used to connect the code to different DSP's. In debug mode data from a target DSP is continuously fetched allowing the user to make real time modifications to the code and get real time feed back of the results.

Numeric intensive development environment

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.
