Development of an analogue microprocessor

Abstract

Progress towards the development of a reconfigurable analogue cell array is reported. The integrated circuit array can be thought of as an Analogue Microprocessor (AMP) analogous in many ways to its digital counterpart. The essential feature of the AMP is that it performs concurrent processing of analogue signals in continuous time. The processors of the array have a simple instruction set, typically ADD, NEGATE, LOG, ANTILOG, INTEGRATE, RECTIFY, etc. The array is digitally field programmable; ultimately yielding a device in the analogue domain comparable to logic cell arrays in the digital domain.
