Predication methods for vector processors

Abstract:

A technique for method for executing instructions in a processor includes receiving a first instruction, receiving a second instruction, identifying a functional unit specified by an opcode contained in an opcode field of the first instruction, selecting a field of the second instruction that contains predicate information based on the identified functional unit, and executing the first instruction in a conditional manner using the identified functional unit and the predicate information contained in the selected field of the second instruction.
