US 4,967,340 A · Adaptive processing system having an array of individually configurable processing components

Abstract

An adaptive processing system for real-time signal processing of one or more input signals in parallel-pipeline fashion is provided. According to the invention, the adaptive processing system includes a random access processor having an array of processing elements each being individually configurable. A man-machine interface receives instructions defining how an input signal is to be processed by the random access processor. A configuration controller responsive to the interface is used to generate configuration data defining a configuration of the random access processor, and data flow between contiguous processing elements thereof, for enabling processing of the input signals according to the insructions. The random access processor is configurable into one or more individually addressable processing arrays which may perform linear or nonlinear operations on an input signal.
