    摘要： An execution unit circuit for use in a processor core provides efficient use of area and energy by reducing the per-entry storage requirement of a load-store unit issue queue. The execution unit circuit includes a recirculation queue that stores the effective address of the load and store operations and the values to be stored by the store operations. A queue control logic controls the recirculation queue and issue queue so that that after the effective address of a load or store operation has been computed, the effective address of the load operation or the store operation is written to the recirculation queue and the operation is removed from the issue queue, so that address operands and other values that were in the issue queue entry no longer require storage. When a load or store operation is rejected by the cache unit, it is subsequently reissued from the recirculation queue.

    摘要： A method of operation of a processor core having multiple parallel instruction execution slices and coupled to multiple dispatch queues coupled by a dispatch routing network provides flexible and efficient use of internal resources. The dispatch routing network is controlled to dynamically vary the relationship between the slices and instruction streams according to execution requirements for the instruction streams and the availability of resources in the instruction execution slices. The instruction execution slices may be dynamically reconfigured as between single-instruction-multiple-data (SIMD) instruction execution and ordinary instruction execution on a per-instruction basis. Instructions having an operand width greater than the width of a single instruction execution slice may be processed by multiple instruction execution slices configured to act in concert for the particular instructions. When an instruction execution slice is busy processing a current instruction for one of the streams, another slice can be selected to proceed with execution.

    摘要： A processor core having multiple parallel instruction execution slices and coupled to multiple dispatch queues by a dispatch routing network provides flexible and efficient use of internal resources. The configuration of the execution slices is selectable so that capabilities of the processor core can be adjusted according to execution requirements for the instruction streams. Two or more execution slices can be combined as super-slices to handle wider data, wider operands and/or vector operations, according to one or more mode control signal that also serves as a configuration control signal. The mode control signal is also used to partition clusters of the execution slices within the processor core according to whether single-threaded or multi-threaded operation is selected, and additionally according to a number of hardware threads that are active.
