Skip instruction carrying out a test with immediate value

摘要

A processor (102) is disclosed herein that may execute an instruction that includes an immediate value and a reference to a register accessible to the processor. The instruction causes the processor to perform a test using the immediate value and the contents of the register referenced in the instruction. Based on the outcome of test, the subsequent instruction is executed or skipped. Further, the instruction includes at least one bit that specifies how the test is to be performed. The bit may specify that the immediate value is to be compared to the register value, or that the immediate value is used to mask the register value and the masked register value has one or more of its bits tested.
