Latest Patents

Among his latest innovations is a patent for a "Method and apparatus for providing overlapping defer phase responses." This invention describes a multiprocessor system utilizing a defer phase response method that allows a deferring agent to take control of the system interface bus and interrupt the standard flow of bus transactions. The deferring agent can anticipate if a continuous stream of defer phase cycles is pending, thus ensuring that the bus control is maintained until these cycles are resolved. This look-ahead capability significantly minimizes any bus dead cycles by prioritizing higher-priority defer data.

Another notable patent is for a "System and method for handling memory requests in a multiprocessor shared memory system." This innovation introduces a request tracking circuit that monitors data requests from various processors. Using a linked list, it efficiently manages multiple pending requests to the same memory address, ensuring that only the oldest request is processed first. This structured approach enhances data retrieval efficiency and streamlines memory operations.
