Request control device, request control method and associated processors

A multiprocessor cooperation architecture comprising:

• a request control means;
• a request storage module, coupled to the request control means;
• a general purpose processor, coupled to the request control means, for unpacking packets of a message received by the multiprocessor cooperation architecture into transformed message segments, for packaging the transformed message segments into queue units, and for placing the queue units into the request storage module;
• a special purpose processor, coupled to the request storage module, for stateful processing of the queue units each time a queue unit is placed into the request storage module by the general purpose processor, wherein the special purpose processor saves and loads states associated with the message while processing the queue units;
• and
• one or more memory storage locations,
• wherein the request control means includes (i) a comparing means configured to determine if an incoming first queue unit corresponds to a same message as a queue unit that pre-exists in the request storage module and (ii) an identifier setting means configured to set a save identifier of the queue unit that pre-exists in the request storage module to indicate not to save a state associated with the message if the first queue unit corresponds to the same message as the queue unit that pre-exists in the request storage module;
• wherein the special purpose processor includes an identifier reading means configured to determine whether to save the state associated with the message, after the queue unit that pre-exists in the request storage module is processed, according to the save identifier of the queue unit that pre-exists in the request storage module, and
• wherein contents of the one or more memory storage locations is a state associated with processing of the message so that processing of the message can be resumed from a same point at a later time during state switching of the special purpose processor.

A request control method comprising:

• stateful processing of a plurality of messages, each message including a plurality of queue units, each message having a state associated with processing of the message, the state being dependent upon processing of the queue units of the corresponding message, each queue unit having a save identifier that indicates whether to save the state associated with processing of its corresponding message;
• determining if a first queue unit incoming to a request control means corresponds to a same message as a queue unit that pre-exists in a request storage module;
• and
• setting a save identifier of the queue unit that pre-exists in the request storage module to indicate not to save a state associated with the message if the first queue unit corresponds to the same message as the queue unit that pre-exists in the request storage module,
• wherein contents of one or more memory storage locations is a state associated with processing of the message so that processing of the message can be resumed from a same point at a later time during state switching of the processor.
