  • Patent number: 10289331
    Abstract: Systems and methods for use in enhancing and dynamically allocating random data bandwidth among requesting cores in multi-core processors to reduce system latencies and increase system performance. In one arrangement, a multicore processor includes a vertical pre-fetch random data buffer structure that stores random data being continuously generated by a random data generator (RNG) so that such random data is ready for consumption upon request from one or more of a plurality of processing cores of the multicore processor. Random data received at one data buffer from a higher level buffer may be automatically deposited into the lower level buffer if room exists in the lower level buffer. Requesting strands of a core may fetch random data directly from its corresponding first level pre-fetch buffer on demand rather than having to trigger a PIO access or the like to fetch random data from the RNG.
    Type: Grant
