- Abstract
- There are considered topologies of the switchable operational blocks for implementing the controlled bit permutations. The operational blocks are constructed using the symmetric permutation networks of different orders. It is described the method for computing the controlling vector value defi-ning implementation of the given bit permutation. Te proposed constructions are very attractive for acceleration of the data transformation algorithms that include different types of the arbitrary fixed bit permutations and variable bit permutations.
