Research of Real-time Clock Synchronization System with Adjustable Decimal Timing of Initial Value

This paper designs a timing of initial values to decimal and can adjust the real time clock synchronization system. By adopting the appropriate system timing algorithm and the initial value for the decimal, automatically modifying its time constant in order to adapt to changes in the crystal frequency, precise time can he achieved. This paper describes the basic principle and key technology of the de sign, and presents a feasible method of software and hardware design.
