摘要： PROBLEM TO BE SOLVED: To provide a duplex system and a system switching method for matching the content of cache memories loaded on both processors when update processing to the cache memories is operated by performing reading and writing through a plurality of ports for the cache memories. SOLUTION: This duplex system is configured to monitor the occurrence of a failure in any of an operational processor 20a and a standby processor 20b, and to, when a failure occurs in the operational processor, switch to the standby processor. A cache memory of each processor has a plurality of ports through which data can be simultaneously read and written. The cache memory controller of the operational processor transfers the update data for the cache memory to the cache memory of the standby processor by using a port different from the port used for updating. The cache memory controller of the standby processor writes the received update data into the cache memory by using a port different from the port used for updating. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an access monitoring method and an access monitoring device for a shared memory, the method and the device enabling access information from an arbitrary processor to a shared memory to be monitored irrespective of type of a multiprocessor system. SOLUTION: A bus interface part 110 of a shared memory board 100 receives a request packet RP where a processor identifier (210_1) and an acquisition request RQ1 (or a release request) of the right to access a shared memory SM are set, from an arbitrary request source processor 210_1 out of a plurality of processors 210_1 to 210_n. In response to the acquisition request RQ1 (or the release request) of the right to access the shared memory SM, the bus interface part 110 sets (or releases) the identifier (210_1) of the request source processor to (or from) the shared memory and generates an answer packet AP showing acquisition ACK1 (or release) of the access right in accordance with setting (or release) of the identifier (210_1) of the request source processor and broadcasts the answer packet to all the processors 210_1 to 210_n.

摘要： PROBLEM TO BE SOLVED: To provide a line test system wherein the test of an emergency notice line is automated to enhance the test quality and the reliability. SOLUTION: A test management apparatus 10 is placed to an attendant board 10-1 to perform user interface control with maintenance personnel and transmits test line information to designate a test line. A bypass line trunk 20a receives a substantial emergency call having arrived during execution of the test and connects the emergency call to an attendant board 10-2. A line switch trunk 30 receives a line switch signal for switching a line to connect the emergency call to the bypass line trunk 20a and to connect a test call to an emergency notice line trunk 20 of a test object through the selected test line. A test control trunk 40 decodes the test line information, recognizes the test line, monitors the state of use of the test line, and transmits the line switching signal for avoiding the closing of the line during the test when the line is idle to perform test control.
