A Logic-in-Memory architecture for large-scale-integration technologies

A computing machine is described which is structured around a distributed logic storage device called the Processing Memory. This machine, the Brookhaven Logic-In-Memory Processor (BLIMP), is meant only as a vehicle for simulating and evaluating its concepts, rather than for eventual fabrication. In particular, it is shown that the architecture used is very well suited to large-scale-integration (LSI) implementation technologies. It was first necessary to redefine the various goals of logic design optimization in the context of LSI implementation. Then an elemental building block of the Processing Memory is described as having evolved from associative memory circuits. It is shown that a computer such as BLIMP which utilizes the Processing Memory concept can meet the goals of design optimization for LSI. Design techniques for this project were developed as they were required. Of particular importance is a simulation system called MODEL, which documents the structure and analyzes the behavior of the proposed system.
