A C++ software environment for the development of embedded signal processing systems

A new environment for the rapid development of embedded signal processing software is described. The environment encourages incremental design via modular and hierarchical structuring of applications, and additional features are included which support the prototyping, testing, implementation, and integration stages of the system design cycle. Written in C++, the environment is comprised of a scripting language for the definition of system components and a class library which includes a basic application framework. Support is provided for incorporating both numeric and symbolic signal representations, as well as integrating multiple signal processing techniques within a single application. A sophisticated control mechanism allows dynamic scheduling of signal processing operations according to algorithmically defined schema. Signal processing applications developed in this environment are themselves objects, and are suitable for embedding within a larger overall system.
