Abstract

A method of profiling disparate communications and signal processing standards. The method begins with selection of a set of communications and signal processing standards for analysis. Next, functions performed by the set of communications and signal processing standards are identified and ranked according to computational intensity. A set of high computational intensity functions are then selected for implementation as kernels, the set of kernels forming a programmable processor that enables implementation of any one of the set of communications and signal processing standards.

designing the programmable application-specific processor in accordance with the kernels selected;

profiling the high computational intensity functions across the set of communications and signal processing standards to identify a common set of sequences of operations and a variable set of sequences of operations; and

defining each kernel as including a fixed computation unit to implement the common set of sequences of operations and a programmable unit to implement the variable set of sequences of operations, the kernels being programmable to implement any one of the set of communications and signal processing standards.
