Abstract

Disclosed is a method for managing an issue queue for fused instructions and paired instructions in a microprocessor. The method includes dispatching a fused instruction to a first entry in a double issue queue; dispatching two paired instructions to a second entry in the double issue queue; issuing the fused instruction during a single cycle to an execution unit in response to determining, by the issue queue logic, that the fused instruction is ready to issue; and issuing, by the issue queue logic, the first instruction of the two paired instructions to the execution unit in response to determining, by the issue queue logic, that the first instruction of the two paired instructions is ready to issue.
