Title: Innovations of Inventor Chau-Shing Hui
Introduction
Chau-Shing Hui is a notable inventor based in Austin, TX (US). He holds a total of 4 patents that showcase his contributions to technology and innovation. His work primarily focuses on systems that enhance the efficiency of computer systems and integrated circuits.
Latest Patents
One of his latest patents is titled "System with DLL." This invention features a shifting delay circuit that provides a variable delay for delaying a source clock. It includes a delay locked loop (DLL) with a delay line that also offers a variable delay for the source clock. The delay line's delay is adjusted by a counter, which is incremented to change the delay. The shifting delay circuit is based on half periods of a reference clock (GCLK) that has a known relationship to the source clock. The total delay for the source clock combines the contributions from both the shifting delay circuit and the delay line. This innovation allows for a smaller delay line in integrated circuits due to the use of the shifting delay circuit.
Another significant patent is the "Method and apparatus to reduce system bus latency on a cache miss with address acknowledgments." This method involves transmitting a value from a system memory device to a lower level of the cache using a system bus. It acknowledges the forwarding of the address from the lower level of the cache after the value is transmitted. The process also includes acknowledging the forwarding of the address from a higher level of the cache in response to the transmission. This approach effectively reduces memory access latency with L2 cache misses and improves address bus utilization.
