A data processing module having a central processing unit and a task management control method and apparatus is disclosed which may comprise: a plurality of task identifiers adapted to identify a task requesting service by the central processing unit; an arbitration system external to the central processing unit adapted to select a task identifier from one of the plurality of task identifiers and to provide to the central processing unit the location of data or at least one instruction, which location is determined by the identity of the task identifier and to provide to the central processing unit the location of at least one instruction to initiate processing of the task, comprising: arbitration value determination logic adapted to determine at least one arbitration value of each task identifier requesting service; arbitration logic adapted to select a task identifier requesting service based upon the at least one arbitration value for each task identifier requesting service. The task identifier for at least some of the task identifiers may be linked to a message queue adapted to hold at least one task related message including data or at least one instruction. The at least one arbitration value may comprise one of a plurality of group identifiers and a priority value associated with each group; and the arbitration logic may be adapted to select a task identifier from among a plurality of task identifiers of different groups based upon the priority value assigned to each respective group. The processing module may be part of a computer and communication link interface, may be implemented on an integrated circuit and may be part of a host bus adapter card. |
