Abstract: An apparatus and a method for synchronizing a clock are provided to improve frequency resolution of a synchronized clock by changing a phase of a clock after changeably selecting clocks having different phase. A clock generating part(120) generates a plurality of clocks having different phase. A first clock selecting part(125) selects one among a plurality of clocks according to a target frequency offset. A first visual information generating part(130) generates visual information. An offset calculating part(140) calculates the target frequency offset which minimizes a time offset between clocks of a master and a slave by using a synchronization message and the visual information. A filtering part(150) filters the target frequency offset. A second clock selecting part(165) selectively outputs one among a plurality of clocks according to the filtered target frequency offset. A second visual information generating part(160) generates visual information by using a clock selected in the second clock selecting part.

Abstract: PURPOSE: A method for settling a communication interruption in an inter-process communication(IPC), is provided to settle a communication interruption, without restarting a system after turning off, when a communication is interrupted by an occupancy of IPC queue resources by a special processor, in an IPC server of a real-time operation system. The method enables to continue an information process operation of other processes, by sacrificing only one or small minority of process, in an operation system held up while many processes process information. CONSTITUTION: A method for settling a communication interruption in an inter-process communication(IPC), comprises the steps of: recognizing a queue pool generation and informing a user of the generation; selecting a sacrificial process among processes existing in an operation system; collecting every queue resources from the selected sacrificial process; resuming a normal operation of the system by making the collected queue resources shared by existing processes.
