Title: The Innovations of Man Cheuk Ng
Introduction
Man Cheuk Ng is an accomplished inventor based in Cambridge, MA. He has made significant contributions to the field of computer systems, particularly in memory hierarchy and data management. With a total of 2 patents, Ng's work focuses on enhancing the efficiency of multiprocessor systems.
Latest Patents
Ng's latest patents include innovative mechanisms for supplying volatile data copies in multiprocessor systems. In a computer system with a memory hierarchy, when a high-level cache supplies a data copy to a low-level cache, the shared copy can be either volatile or non-volatile. When the data copy is later replaced from the low-level cache, if the data copy is non-volatile, it needs to be written back to the high-level cache; otherwise, it can be simply flushed from the low-level cache. The high-level cache can employ a volatile-prediction mechanism that adaptively determines whether a volatile copy or a non-volatile copy should be supplied when the high-level cache needs to send data to the low-level cache. An exemplary volatile-prediction mechanism suggests the use of a non-volatile copy if the cache line has been accessed consecutively by the low-level cache. Furthermore, the low-level cache can employ a volatile-promotion mechanism that adaptively changes a data copy from volatile to non-volatile according to some promotion policy, or changes a data copy from non-volatile to volatile according to some demotion policy.
