Patent ID: 8468429

Claim:
An apparatus comprising a reconfigurable cyclic shifter adapted to cyclically shift a group of N sets of bits on a set-by-set basis, N>2, to change a set-ordering of the N sets in the group, wherein: the reconfigurable cyclic shifter is selectively configurable to operate in a first operating mode to cyclically shift the N sets of bits in the group on a set-by-set basis to change a set-ordering of the N sets, in which each set of bits in the N sets has a first number of bits; and the reconfigurable cyclic shifter is selectively configurable to operate in a second operating mode to cyclically shift the N sets of bits in the group on a set-by-set basis to change a set-ordering of the N sets, in which each set of bits in the N sets has a second number of bits different from the first number of bits.
