Abstract
A data processing systemincludes a single instruction multiple data register fileand single instruction multiple processing circuitry. The single instruction multiple data processing circuitrysupports execution of cryptographic processing instructions for performing parts of a hash algorithm. The operands are stored within the single instruction multiple data register file. The cryptographic support instructions do not follow normal lane-based processing and generate output operands in which the different portions of the output operand depend upon multiple different elements within the input operand.
