Intel® PCH EG20T IEEE1588 Hardware Assist Driver: Guide
This document describes the IEEE1588 hardware assist driver interfaces exposed to the user-mode applications and how to use those interfaces to drive the IEEE1588 hardware to achieve time synchronization on Ethernet and CAN. In a distributed control system containing multiple clocks, individual clocks tend to drift apart. A correction mechanism is necessary to synchronize the individual clocks to maintain global time, which is accurate to some requisite clock resolution.
The IEEE1588-2008 standard defines a precision clock synchronization protocol for networked measurement and control systems, including several messages used to exchange timing information.
The hardware assist logic required to achieve precision clock synchronization using the IEEE1588-2008 standard depends on the implementation.
