Abstract
A mechanism for predicated execution of instructions within a parallel processor executing multiple threads or data lanes is disclosed. Each thread or data lane executing within the parallel processor is associated with a predicate register that stores a set of 1-bit predicates. Each of these predicates can be set using different types of predicate-setting instructions, where each predicate setting instruction specifies one or more source operands, at least one operation to be performed on the source operands, and one or more destination predicates for storing the result of the operation. An instruction can be guarded by a predicate that may influence whether the instruction is executed for a particular thread or data lane or how the instruction is executed for a particular thread or data lane.
