  • Non-uniform bus (NUB) interconnect protocol for tiled last level caches
    Patent number: 10740236
    Abstract: A method and apparatus are provided. The apparatus includes a plurality of central processing units, a plurality of core input/output units, a plurality of last level cache memory banks, an interconnect network comprising multiple instantiations of dedicated data channels, wherein each dedicated data channel is dedicated to a memory transaction type, each instantiation of dedicated data channels includes arbitration multiplexors, and each dedicated data channel operates independently of other data channels.

  • Prefetch address generation implementing multiple confidence levels
    Publication number: 20060248280
    Abstract: Adjusting the confidence level of prefetch circuitry in generating outstanding prefetch address of a detected strided stream. In one example, the number of outstanding prefetches allowed is adjusted based on a determination of whether a prefetch to a prefetch address is used in a data processing system. With some systems, the higher the confidence level, the more outstanding prefetches are allowed.
