Abstract
An execution slice circuit for a processor core has multiple parallel instruction execution slices and provides flexible and efficient use of internal resources. The execution slice circuit includes a master execution slice for receiving instructions of a first instruction stream and a slave execution slice for receiving instructions of a second instruction stream and instructions of the first instruction stream that require an execution width greater than a width of the slices. The execution slice circuit also includes a control logic that detects when a first instruction of the first instruction stream has the greater width and controls the slave execution slice to reserve a first issue cycle for issuing the first instruction in parallel across the master execution slice and the slave execution slice.
