Abstract
An apparatus for processing data is provided comprising processing circuitry having permutation circuitry for performing permutation operations, a register bank having a plurality of registers for storing data and control circuitry responsive to program instructions to control the processing circuitry to perform data processing operations. The control circuitry is arranged to be responsive to a control-generating instruction to generate in dependence upon a bit-mask control signals to configure permutation circuitry for performing permutation operation on an input operand. The bit-mask identifies within the input operand the first group of data elements having a first ordering and a second group of data elements having a second ordering and the permutation operation is such that it preserves one of the first ordering and the second ordering but changes the other of the first ordering and the second ordering.
