Latest Patents

One of Pak Kuen Fung's latest patents is a "Programmable Architecture Fast Packet Switch." This invention provides a testbed for evaluating prototype architectures and traffic management algorithms. The programmable switch is designed as an add-on peripheral to a conventional computer system, which includes a host central processing unit (CPU). It features multiple port processors that communicate with port interfaces, allowing for high data rate communication. The switch fabric is realized in a multiple slice fashion, utilizing programmable logic devices. A central arbiter, also implemented in programmable logic, controls the routing of cells within the switch. This innovative design enables full-speed operation as a fast packet switch, ensuring accurate evaluation results.

Another significant patent is related to "Sequentially Comparing Content Addressable Memory." This invention describes a content addressable memory (CAM) that allows for sequential matching of tags stored in the CAM to a target tag. The CAM consists of tag memory made up of tag cells and a data cache. Each tag cell is structured like a conventional RAM cell but includes a multiplexing switch at its output. The tag compare circuit, external to the tag memory, compares bits from each cell in a selected column to a bit of the target address. This process continues until a mismatch occurs, showcasing the efficiency of the tag compare circuit.
