Latest Patents

Jose Renau Ardevol holds a patent titled "Combining a remote TLB lookup and a subsequent cache miss into a single coherence operation." This invention presents techniques aimed at minimizing address-translation latency and the serialization latency that results from combined TLB (Translation Lookaside Buffer) and data cache misses. The disclosed technology enables last-level TLB structures of multiple multiprocessor nodes to collaborate, acting as either a distributed shared last-level TLB or a directory-based shared last-level TLB. This sharing technique amplifies the total amount of useful translations cached, thereby decreasing page-table walks and enhancing overall performance. Additionally, his invention allows for the fusion of TLB and cache misses, enabling the overlap of latency during data coherence operations with address translation and data cache access, resulting in improved memory operation efficiency.
