Abstract

See full text

A data processing apparatus, method and computer program that perform an operation on one data element such as a register and conditionally select either that register or a further register on which no operation has been performed. The apparatus includes an instruction decoder configured to decode at least one conditional select instruction specifying a primary source register, a secondary source register, a destination register, a condition, and an operation to be performed on a data element from the secondary source register. Data processing operations are controlled by the instruction decoder and the data processor is responsive to the decoded at least one conditional select instruction where the condition does not have the predetermined outcome to form the resultant data element from the data element from the primary register and to store the resultant data element in the destination register.
