Title: Method for start-up synchronization of processors and its synchronization device
Inventor: TERADA KAZUTO
IPC: H04W88/02
Filed: 1994-02-17
Abstract: PURPOSE:To eliminate a start-up time lag of processors by allowing each processor to be in standby till start processing of another processor finishes after its own starting processing and then to execute succeeding processing. CONSTITUTION:A port (a) is used for a setting end notice means 11n to inform it to another processor Pn that one processor Pm finishes its own initial setting and its level is switched from an L level into an H level when the initial setting of the processor Pm is finished. On the other hand, the other processor Pm uses the port (a) for a discrimination means 12n to discriminate whether or not the initial setting of the processor Pn is finished based on whether or not the port (a) is set to an H level. Since the timing of the start-up processing end of both processors Pm, Pn is completely synchronous with each other by the operation above, an error signal caused by start-up time lag of the processors is not outputted to an exchange.
