The cube-connected-cycles: A versatile network for parallel computation

Abstract

We introduce a network of processing elements, the cube-connected-cycles (CCC), complying with the present technological constraints of VLSI design. By combining the principles of parallelism and pipelining, the CCC can emulate the cube-connected machine with no significant degradation of performance but with a much more compact structure. We describe in detail how to program the CCC for efficiently solving a large class of problems, which includes Fast-Fourier-Transform, sorting, permutations, and derived algorithms. The CCC can also be used as a general purpose parallel processor.
