Abstract

The cube-connected cycles network is suitable for realization in VLSI, since it satisfies the properties of degree boundedness of the nodes (=3), and regularity of layout. Another network called the cubical ring-connected cycles (CRCC) is proposed that has all the desirable features of the cube-connected cycle (CCC) and is single-cycle fault tolerant as well. The degree of each processor is less than or equal to four, the number of processors increases from 2/sup r+s/ to 2/sup r/(2/sup 2/+1), for integers r and s, and the number of links increases by a factor of one-third over the corresponding CCC. Reliability improvements of the CRCC network over the CCC are studied. A regular layout scheme suitable for VLSI implementation of the CRCC is presented. Reconfiguration techniques under failures of processors in the CRCC are discussed.
