Memory systems for highly parallel computers

Some recent developments in computer memories are discussed, and proposals are made to enhance the memory systems of highly parallel SIMD (single instruction multiple data) computers. The topics covered include increases in density and speed; adding new logic functions to memory chips; local autonomy in addressing; a parallel indexed RAM (PIRAM); impact of memory on numerical computation in SIMD; routing data among processing elements (PEs); bottlenecks; iconic and symbolic processing; a mesh-interfacing memory chip; bimodal memory system; and local address autonomy using PIRAMs.<
