Abstract

See full text

Swapping of bits between different words of a memory is accomplished by a single permutation means. The single permutation means generates actual address bits for all the bit positions in a memory word. These actual address bits are in a local store. Each time a memory word is accessing the locations of the bits are substituted for logical address bits and fed to the decoders of the different bit positions in the memory word being accessed.
