Latest Patents

Uday Kumar Reddy Vengalam holds a patent for "Cost-driven prefetching." This patent describes systems and techniques for cost-based prefetching. In one example, a processor includes a cache system with a hierarchy of one or more cache levels and an instruction prefetcher associated with a cache level of the cache system. The instruction prefetcher encodes fetch requests to a prefetcher table and determines a cost associated with each entry based on the memory level from which the instructions were fetched. The instruction prefetcher evicts entries in the prefetcher table based on the cost associated with corresponding fetch requests in response to adding new entries. These techniques effectively hide instruction fetch latency that a processor frontend experiences with workloads that have code working sets that do not fit in higher levels of the cache system. Uday Kumar Reddy Vengalam has 1 patent to his name.
