Universal serial bus time synchronization: abstract simplified (18334394)

• This abstract for appeared for patent application number 18334394 Titled 'Universal serial bus time synchronization'

Simplified Explanation

This abstract describes an apparatus that includes various components, a distributed timebase circuit, an interface, and a Time Synchronization Circuit (TSC). The purpose of this apparatus is to provide a consistent time measurement by synchronizing local timebases to a global timebase. The interface is designed to connect to multiple devices, and transmissions on the interface are divided into frames. The time on the interface is determined by a frame number. The TSC captures two timestamps simultaneously - one based on the frame number and another based on the local timebase. These timestamps help correlate the time on the interface to the consistent time measurement.

Original Abstract Submitted

An apparatus includes components, a distributed timebase circuit, an interface and a Time Synchronization Circuit (TSC). The timebase circuit is configured to provide local timebases in physical proximity to the components, and synchronize the local timebases to a global timebase so as to provide a consistent time measurement. The interface is configured to be coupled to one or more devices. Transmissions on the interface are logically divided into a plurality of frames. Time on the interface is defined based on a frame number identifying a particular frame. The TSC is configured to capture a first timestamp based on the frame number corresponding to a point in time on the interface, and to concurrently capture a second timestamp based on a local timebase corresponding to the point in time, wherein the first timestamp and the second timestamp correlate time on the interface to the consistent time measurement.
