Latest Patents

Barroso holds a patent titled "Method and system for detecting and resolving virtual address synonyms in a two-level cache hierarchy." This patent describes a method where L cache synonyms in a two-level cache system are detected and resolved by logic within the L cache. The system maintains duplicate copies of the L cache tags and state, known as "Dtags." When a miss occurs in the L cache, the Dtags in the second-level cache are searched for synonyms. If a synonym is found, the L cache is notified of the location of the requested cache line, which is then copied to the location of the miss, invalidating the original cache line. The Dtags are subsequently updated to reflect these changes.

Career Highlights

Barroso is currently employed at Hewlett-Packard Development Company, L.P., where he continues to innovate in the field of computer architecture. His work has significantly impacted the efficiency of cache systems, making them more effective in handling data retrieval processes.
