摘要:
In a multiprocessor system having a plurality of processors, each of identical construction, each processor is internally equipped with a fixed address supply source which generates a non-unique fixed address for accessing a common memory unit over commonly connected bus lines, and a sequential state indicate signal generator for generating a logic "1" or "0" synchronizing signal when a special condition (for example, interrupt) occurs with respect to the processor.A shared memory access control system for a multiprocessor system, as above described, includes circuitry, external to and associated with at least each processor except for one processor, responsive to the synchronizing signal from its respective processor for modifying the non-unique fixed address from the respective processor so that, as a result, each processor is able to address the common memory over the commonly connected bus lines with a unique fixed address.

A direct memory access control (DMAC) system, in a data processing system, includes at least a central processing unit and a memory, the memory being capable of storing and providing data in any one of several predetermined formats. A plurality of input/output control ports, each connecting a respective input/output device to a common data bus, control data transfer in either direction between the device and the memory. A direct memory access control unit is connected to the common data bus for receiving an access request signal from any of the plurality of input/output control ports, and is connected to the memory for providing thereto, in response to the access request signal, instructions at least as to the size and desired format of the data transfer. A bus switching unit connects the common data bus to the memory, and is connected to the direct memory access control unit for receiving the instructions. The bus switching unit is responsive to the direct memory access control unit for interfacing the memory to the common data bus in such a manner as to cause the data transfer to be of the desired format.

To make an electronic value usable for both service on a network and service in the real world while ensuring security, convenience and economical efficiency, the electronic value issued for a user is controlled on an electronic wallet of a private electronic value bank, the electronic value controlled on the electronic wallet of a bank is cached in a mobile electronic wallet on a smart card of a user's portable terminal 5, and the electronic wallet is linked such that it is operated via the network when the mobile electronic wallet is operated. When the electronic value on the smart card is used for the service provided in a real environment such as a ticket gate of a train station, on-line transaction does not occur every time it is used, but the electronic wallet of the bank is updated when the portable terminal and the bank communicate later.

To provide a system for processing program information in which the display structure of a program table can freely be changed in accordance with a requirement or a taste of an audience, the system for processing program information is constructed to include program information storage means 1 for storing program information, and program table display means 4 for two-dimensionally displaying a program table following two axes in accordance with two attributes 102 and 103 among attributes given to each piece of program information, to make the program table 101 for two-dimensionally displaying programs with two axes of free attributes. For the audience, program tables of various constructions can be displayed on the display means at will and in respective program retrieval operations, the program table easy to look for a program can be obtained. An objective program can be found in a short time by coming up with ideas for the extraction of the program or the like, and this is useful for making a broadcast view plan of himself.

To provide a system for processing program information in which the display structure of a program table can be freely changed in accordance with a requirement of or the taste of an audience, the system for processing program information is structured to include program information storage means 1 for storing program information, and program table display means 4 for two-dimensionally displaying a program table employing as the two axes, two attributes 102 and 103 selected from among all of the attributes that have been given to each piece of program information, to make the program table 101. For the audience, program tables of various constructions can be displayed on the display means at will and in respective program retrieval operations, a program table that is easy to use to search for a program can be obtained. An specific desired program can be found in a short time by selecting key word(s) related to each program and extracting them from the program or the like. This is useful for an audience member to make a plan of desired broadcasts for himself.
