Latest Patents

Laptev is associated with 1 patent, titled “Computer Caching Methods and Apparatus.” The invention selects different replacement sets when cache misses occur simultaneously on multiple ports, allowing replacements to proceed at the same time through separate write ports. In some embodiments, each cache set has its own write ports, while its tag memory has a dedicated write port and multiple read ports.

The patent describes a tree-based replacement policy, such as tree LRU. For a single cache miss, the search for a replacement set begins at the tree’s root. When multiple misses occur simultaneously, the search begins at a level with enough nodes to assign a separate starting node to each miss.

Career Highlights

Laptev’s listed company affiliation is Sun Microsystems, Inc. His patent reflects work on cache architecture and replacement strategies designed to support concurrent operations in multi-port systems.

Collaborations

Laptev’s listed coworkers include Zinaida Nikolaevna Zaitzeva and Andrey Alexe'evich Vechtomov.

Conclusion

Michael Victorovich Laptev’s patent presents a tree-based approach to selecting cache replacements concurrently, highlighting his contribution to computer caching methods and apparatus.
