Summary :

This paper gives another consideration for Benes rearrangeable IN to be constructed from cascading two blocking Interconnection Networks (IN), in an attempt to make such type of IN more practical for parallel systems. The reverse binary n-Cube, and binary n-Cube multi-stages INs, have been used to construct rearrangeable Benes IN. The control algorithm has two construction phases. The first phase is to confirm and transform any arbitrary permutation into the conflict free form (to control the reverse binary n-Cube IN). The second phase uses the mechanism of Bit-Tag control to map such conflict free permutations and control the second half of Benes IN, (i.e., the Cube). The second phase receives its input from the first phase output, after being transformed into a conflict free permutation. Such construction increases the flexibility in the design of Rearrangeable Multi-stage IN.
