Application of one-chip signal processor in digital controller implementation

This paper describes the application of the Intel 2920 one-chip signal processor for digital control. The architecture, data conversion, instruction set, and input/output of the processor are illustrated with particular emphasis on the features that make it suitable for digital control and signal processing applications. It is demonstrated how the - transfer function or difference equation of a digital controller can be programmed on the processor. A linear and one nonlinear controller are used as examples for implementation. Available design tools and software packages are introduced; the factors that one must consider in using the chip for control purposes are discussed.
