Abstract
Apparatus and methods for real-time control using a data processor. In one aspect, the invention comprises an improved processor having one or more extension instructions (and associated supporting pipeline hardware) which are specially adapted for use in a real-time control algorithm running on the processor. In one exemplary embodiment, the processor is a 32-bit pipelined RISC device having custom multiply (CMUL) and multiply-accumulate (CMAC) instructions added to the extension instruction set to optimize algorithm performance in real-time linear time-invariant (LTI) applications. Specialized extension hardware, and methods for generating a processor design adapted for real-time control applications are also disclosed.
