Abstract
A data processing apparatus having processing circuitry, a scalar register bank and a vector register bank, including decoding circuitry arranged to decode a sequence of instructions to generate control signals for the processing circuitry. The decoding circuitry is responsive to a decode modifier instruction within the sequence of instructions to alter decoding of a subsequent scalar instruction in the sequence by mapping at least one scalar operand specified by the subsequent scalar instruction to at least one vector operand in the vector register bank, and, in dependence on the scalar operation specified by the subsequent scalar instruction, determining a vector operation to be performed on at least a subset of the operand elements within the at least the one vector operand. Such an approach enables a wide variety of vector operations to be specified without the need to individually define separate vector instructions for those vector operations.
