Latest Patents

One of his latest patents is titled "Prefetch optimization in shared resource multi-core systems." This invention describes an apparatus and method for optimizing prefetch throttling, which potentially enhances performance, reduces power consumption, and maintains positive gains for workloads that benefit from prefetching. The optimizations allow for bandwidth congestion and prefetch accuracy to be considered as feedback for throttling at the source of prefetch generation. When congestion is low, full prefetch generation is permitted, even if the prefetch is inaccurate, due to available bandwidth. Conversely, when congestion is high, the determination of throttling relies on prefetch accuracy. If the accuracy is high, less throttling is needed, as the prefetches are effectively utilized. However, if the accuracy is low, more throttling is necessary to conserve power, as the prefetches do not enhance performance.

Another significant patent is "Guaranteed service in a data network." This invention involves a data controller that includes a traffic pattern collector to observe data traffic patterns comprised of data packets. The traffic service engine receives data concerning the traffic pattern and determines a data flow specification that allows each data packet to be transferred within a specified delay upper bound. The minimum data flow specification is determined using an algorithm known as the Any-Delay TB Algorithm.
