    摘要： A generic method and apparatus for managing semaphores in a multi-threaded processing system has a storage area for each of the threads in the processing system. Each storage area includes a first part for storing at least one indicia for identifying at least one unique semaphore from a plurality of semaphores utilized by the multi-threaded processing system and a second part for storing an indicia for indicating a locked status for the stored semaphore. A thread requiring a semaphore sends a semaphore lock request to the semaphore manager which examines the contents of all of the storage areas to determine the status of the requested semaphore. If the requested semaphore is not locked, it is locked for the requesting thread by inserting the requested semaphore and locked status in the memory location assigned to the requesting thread.

    摘要： A system and method of data flow management, particularly in a multiple network processor architecture where a plurality of independent processing units are simultaneously processing information from different frames of input information. The present invention includes first-in-first-out files identifying the individual frames and correlating the frames with the processor to which the frames have been assigned for processing as well as a first-in-first-out file of processed frames for each processor to allow the frames to be processed independently, then reassembled into the same order as the frames had been received without communication between the independent processors. Additionally, the present system supports newly-created frames as well as the concept of flushing the system without regard to frame order whereby frames are sent out to the network as the processing is completed without regard to input order, overriding the system of putting the output frames in the same order as the input frames were received from the network.

    摘要： A system and method for handling speculative read requests for a memory controller in a computer system are provided. In one example, a method includes the steps of providing a speculative read threshold corresponding to a selected percentage of the total number of reads that can be speculatively issued, and intermixing demand reads and speculative reads in accordance with the speculative read threshold. In another example, a computer system includes a CPU, a memory controller, memory, a bus connecting the CPU, memory controller and memory, circuitry for providing a speculative read threshold corresponding to a selected percentage of the total number of reads that can be speculatively issued, and circuitry for intermixing demand reads and speculative reads in accordance with the speculative read threshold. In another example, a method includes the steps of providing a speculative dispatch time threshold corresponding to a selected percentage of a period of time required to search a cache of the computer system, and intermixing demand reads and speculative reads in accordance with the speculative dispatch time threshold.
