    摘要: A method, and apparatus are provided for preventing livelocks in processor selection of load requests in a multiprocessor (MP) system. On random occasions a selection mechanism is changed for first holding up all requests and then a random selection is made. Then a round robin selection mechanism is used for further requests. A livelock-preventing selection mechanism includes a pair of linear feedback shift registers (LFSRs), each LFSR for generating pseudo random values.
