Title: CLOCK SKEW CORRECTION METHOD, DEVICE AND SYSTEM
Abstract:
Provided are a clock skew correction method, device and system. The method comprises: determining at least two assemblies (101); when a clock generation source transmits a clock signal for each of the assemblies, determining a cycle duration of the clock signal, and calculating a delay parameter of each of the assemblies (102); selecting one slave assembly and at least one master assembly from the at least two assemblies (103); according to the delay parameter of the slave assembly, correcting a clock phase corresponding to each of the master assemblies (104); and with regard to each of the master assemblies, according to the cycle duration and the corrected clock phase corresponding to the master assembly, generating a corrected clock corresponding to the master assembly (105). The solution achieves the correction of clock skew.
