Abstract
A data processing system is provided with a digital signal processor (DSP) which has a shuffle instruction for shuffling a source operand ( ) and storing the shuffled result in a selected destination register ( ). A shuffled result is formed by interleaving bits from a first source operand portion with bits from a second operand portion. A de-interleave and pack (DEAL) instruction is provided for de-interleaving a source operand. The shuffle instruction and the DEAL instruction have an exactly inverse effect. The DSP includes swizzle circuitry that performs interleaving or de-interleaving in a single execution phase.
