Title: PROCESSOR AND METHOD OF HANDLING AN INSTRUCTION DATA THEREIN
Abstract:
A method can be performed in a processor integrated circuit having an instruction decoder (18, 118) and a plurality of shared resources (14, 114), a resource tracker (16, 116) having a plurality of credit units (22) associated to corresponding ones of the shared resources (14, 114) in a manner to be updatable based on availability of the shared resources (14, 114), a resource matcher (28, 128) connected to receive a resource requirement signal from the decoder (18, 118) and connected to receive a resource availability signal from the resource tracker (16, 116). 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 (22), and preventing the resource matcher (28, 128) from performing a subsequent determination for given period of time after the positive determination.
