With a total of 5 patents to his name, Lefsky's work has had a lasting impact on the efficiency and reliability of computing systems.
Latest Patents
One of Lefsky's latest patents is titled "High Availability Cache Organization." This invention describes a high availability set associative cache memory designed to serve as a buffer between main memory and a central processing unit. The cache memory includes multiple sets of cache cells, each containing a data field, a tag field, and a status field. The status field features a force bit that indicates a defective cache cell when set, allowing the system to suppress output from that cell and effectively map it out of operation. This ensures that as long as one cell in a set remains operational, the system can continue functioning seamlessly.
Another significant patent by Lefsky is the "Clock Skew Avoidance Technique for Pipeline Processors." This technique addresses the issue of skew compensation in pipelined processors, which occurs between first and second clock signals. The invention provides a method for the proper transfer of information between stages, even when clock signals may have a skew greater than the inter-stage delay. A holding or latching mechanism is implemented between stages to retain previous stage data for clocking into the subsequent stage register.
