  • Patent number: 10915359
    Abstract: A technique for scheduling processing tasks having different latencies is provided. The technique involves identifying one or more available requests in a request queue, where each request queue corresponds to a different latency. A request arbiter examines a shift register to determine whether there is an available slot for the one or more requests. A slot is available for a request if there is a slot that is a number of slots from the end of the shift register equal to the number of cycles the request takes to complete processing in a corresponding processing pipeline. If a slot is available, the request is scheduled for execution and the slot is marked as being occupied. If a slot is not available, the request is not scheduled for execution on the current cycle. On transitioning to a new cycle, the shift register is shifted towards its end and the technique repeats.

  • Publication number: 20200167287
    Abstract: A technique for prefetching data for a cache is provided. The technique includes detecting access to a data block. In response to the detection, a prefetch block generates proposed blocks for prefetch. The prefetch block also examines prefetch tracking data to determine whether a prefetch group including the proposed blocks is marked as already having been prefetched. If the group has been marked as already having been prefetched, then then prefetch block does not prefetch that data, thereby avoiding traffic between the prefetch block and the cache memory. Using this technique, unnecessary requests to prefetch data into the cache memory are avoided.
