Abstract
The invention includes receiving a first instruction in an in-order execution processing pipeline; starting execution of the first instruction; determining a first set of internal operation bits indicating a prospective value of control bits upon complete execution of the first instruction; determining whether the first instruction is a committed instruction; receiving a second instruction in the in-order execution processing pipeline before execution of the first instruction completes; determining a second set of internal operation bits based on: a) the first set of internal operation bits if the first instruction is a committed instruction; or b) a set of internal operation bits of a last committed instruction if the first instruction is not a committed instruction; and starting execution of the second instruction in the in-order execution processing pipeline before execution of the first instruction completes using the second internal operation bits. Numerous other aspects are provided.
