Title: Method for correcting clock of processor
Inventor: KIM JAE HYEON
IPC: H04Q1/30
Filed: 2002-09-27
Abstract: PURPOSE: A clock correcting method in an exchange processor is provided to secure stability of a clock between processors by minutely dividing a clock correction unit up to an msec unit and stably operate a system by adding a statistical function for a monitoring result. CONSTITUTION: An MP(Main Processor) stores an OMP(Operating Maintenance Processor) clock and an MP clock in units of msec and sec according to clock information received from an OMP(S100). 1000 is multiplied to the data stored in units of sec and then added to the data stored in units of msec(S110). A result value obtained by subtracting the OMP clock from the MP clock is set as 'diff'(S120). It is checked whether the diff value is greater than or the same as -1000 or smaller than or the same as 1000 in order to determine whether to perform a correction(S130). The diff value is divided by 1000 and its absolute value is taken to be stored as diff(sec), and an OMP(msec) absolute value is subtracted from 1000 and then stored as diff(msec)(S140). The diff value is divided in units of 200msec and then stored(S150). It is checked whether 'diff' is greater than '0'(S160). If 'diff' is greater than '0', diff(sec) is subtracted from the MP clock(sec) and stored as an MP clock(sec) value, and sleep{diff(sec)} is performed(S310). After a delay is made as long as delay time, the MP performs a set time to reset sec unit time(S320). If 'diff' is smaller than '0', a value obtained by adding diff value and 1 is added to the MP clock(sec) and stored as an MP clock(sec), and the sleep{diff(sec)} is performed(S210). After delay is made as long as delay time, the MP performs a set time to reset sec unit time(S220).
