Title: Godwin Gerald Arulappan: Innovator in USB Technology
Introduction
Godwin Gerald Arulappan is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of USB technology, holding a total of 9 patents. His work focuses on enhancing the functionality and efficiency of USB controllers and related systems.
Latest Patents
Among his latest patents are innovations such as a Universal Serial Bus (USB) controller and a method of operating a USB controller. This USB controller is designed to receive an isochronous timestamp packet (ITP) from a host device, which includes a current time value and a delay value associated with each hub. The controller hardware initiates a counter, sends a link delay measurement (LDM) link management packet (LMP) request to the nearest upstream hub, and stores timestamps for both the request and response. The controller software then calculates the link delay based on these timestamps and adjusts the counter accordingly.
Another significant patent involves a method and apparatus to save power in USB repeaters and re-timers. This innovation intercepts packets from the host to predict data traffic direction, allowing the circuitry of a peripheral port to be selectively turned off or on. This technique enhances power efficiency by anticipating the flow of data between the host and peripheral devices.
