摘要： PURPOSE:To simplify the control of a line concentration stage, by giving a logical 2-tier control and thus secure a separation of function among the processors as well as the independence of function. CONSTITUTION:The line concentractor LC that performs a concentration of subscriber lines consists of the line concentration control processor LC-LNP that performs controls within the LC plus the line concentration channel device LC-SP that stores a plural number of subscribers SUB. The calling of the SUB connected to the LC is sent to the trunk control processor TKP within the distribution stage device DIS-SW via the control information line LINE. The processor TKP transfers the information to the processor CP from the information bus BUS without giving any logical decision if the information is addressed to the central control processor CP. The logical decision of the calling detection signal is controlled by the processor CP, and a connection is given between the originating register trunk within the trunk device group TRK and the call line SP between the LC and the SP for reception of the dial figures of the SUB. Thus an isolation is secured for the controls among the processors.

摘要： PURPOSE:To enable to reduce the processing interrupting time against failure, by performing memory protection check at the same time as write-in to an existing storage device and making write-in to a spare system storage device after the memory protection check. CONSTITUTION:Processors CC#0, CC#1 read required information from an existing storage device and write in the processing information to the existing storage device IM#0. In this case, the result of the memory protection check at the device IM#0 is transmitted to the processor CC#0, and the check for the spare storage device is made thereafter. If normal, the CC#0 writes in the information to the spare storage device IM#1 for processing with the existing device. If not normal, the processing is interrupted at an interruption request signal IS, the information FFG at the interruption is written in the specific area of the device IM#0 for saving. A system managing device SCTL which stops the device CC#0 with an emergency circuit EMA sets the information saved in the specific area of the IM#0 to the CC#1 to change the device IM#1 into the existing device.

摘要： PURPOSE:To prevent the competition of events transferred between processors unitedly by giving discrimination information to a call in exchange processing and by referring to the discrimination information. CONSTITUTION:Trunk control processors TKPi and TKPj are connected respectively corresponding to digital signal processors DSGE, and the multiprocessor exchange processing system is composed of call processors CPi and CPj with decentralized loads, common memory CM, and network NW. When CPi accepts the start of a call, the call is given ID as an identifier, and a circuit number is also given ID as a circuit event and sent to CPi, which stores CM with it. To TKPj for the call, an event of ID and the circuit number is sent and, while stored, sent to CPj. When this event is received, CPj collates ID of an assigned event with that of the event from TKPj and, when those IDs agree, executes the event.

摘要： PURPOSE:To decrease the queuing for the access system of the common memory, by stopping the operation of the processor if the common memory is under access and then starting again the processor via the access end order of other processor. CONSTITUTION:When processor CPi gives the access to the conflicting data within common memory CM, the checking is given whether the data is under access by other processor. And in case switch SW is under operation when memory CM is being carried out, control unit CTL within common memory control unit CMC registers both processor CPi and switch SW. Then the SW is made idle after execution of processor CPj, and the queuing of CPi is released. And the execution of CPi is started. As the restart is possible by the access end order, the queuing can be decreased.

摘要： PURPOSE:To simply perceive a sense of an out-head sound image locarization by using a storage card exclusive for a person in which person dependent out- head sound image locarization information is stored. CONSTITUTION:The person dependent out-head sound image locarization information resulting from applying convolution operation to inverse headphone impulse information and spatial impulse information is stored in a storage card 9. When the storage card 9 is loaded to a storage card container 8, a data content of the storage card 9 is stored in each memory of right ear use and left ear use convolution computing elements 3a, 4a. A digital input audio signal 1 and the person dependent out-head sound image locarization information are subject to convolution operation in the computing element 3a and the result is outputted to a right ear use phone of a headphone 7 via a right ear use D/A converter 5. Similarly, the input signal is calculated by the computing element 4a for the left ear and the result is outputted to the left ear use phone. Thus, even when the device is used for listening by lots of unspecified persons, a sense of an out-head sound image locarization is perceived accurately by using the person dependent storage card.

摘要： PROBLEM TO BE SOLVED: To enable a high-compressibility and low-price processor to provide high-quality reproduced sounds with a little memory capacity and manipulated variable by previously applying a positive or negative polarity to respective pulse position candidates on a position code book while making a positive/ negative code book correspondent to each position code book. SOLUTION: The positive/negative direction at the position of a pulse is determined for each set only by the position code of the pulse. Namely, position code books 5-11 to 5-1N are respectively combined with positive/negative code books 7-11 to 7-1N and made correspondent. For example, a positive/negative code corresponding to each pulse position, which can be designated by the position code book 5-11, is predetermined on the positive/negative code book 7-11. Then, positive and negative codes from the positive/negative code books 7-11 to 7-1N are respectively multiplied to the respective output pulses of pulse generating parts 5-21 to 5-2N by positive/negative code multiplying parts 5-31 to 5-3N. Thus, N pulses determined as needed are collected and one positive/ negative code is multiplied by an entire code multiplying part 7-2.
