Abstract: The method can be performed in a processor integrated circuit having an instruction decoder and a plurality of shared resources, a resource tracker having a plurality of credit units associated to corresponding ones of the shared resources in a manner to be updatable based on availability of the shared resources, a resource matcher connected to receive a resource requirement signal from the decoder and connected to receive a resource availability signal from the resource tracker. The method can include: performing a determination of whether or not the resource requirement signal matches the resource availability signal, and, upon a positive determination, dispatching a corresponding instruction data, updating the status of a corresponding one or more of the credit units, and preventing the resource matcher from performing a subsequent determination for given period of time after the positive determination.
