Abstract

This article presents a precise synchronization algorithm based on status tracking and locking mechanism. Tracking execution state of triple computer and running state of time base counter through dual state machine not only can implement precise synchronization of TMR computer, making status synchronization precision and time-base synchronization precision below 30ns, but also save valuable interconnection resource, reduce implementation cost and other overhead of system resources.
