摘要:
In a data processing system, a plurality of modules connected to a system bus thereof are assigned with identifiers. When a source module initiates a split read access to another module, the source module sends an address of the access destination module and an identifier of the source module. When sending a response to the source module, the destination module returns response data and the identifier of the source module thereto. Checking the identifier from the destination module, the source module determines the response data returned as a response to the initiated access.

In a video storage and delivery apparatus and corresponding system, video data items are simultaneously supplied to a plurality of users while guaranteeing the time axis and the picture quality of the video data. The apparatus includes a frame address table which indicates a storage location in the apparatus of each frame of video data to start a special reproduction or a reproduction at a desired frame and a control unit controlling a switch bus connecting a plurality of video storage and delivery apparatuses to a plurality of channels so as to conduct data transfers via the switch bus between the apparatuses and between video reproduction devices of the users. From an optical disk data storage storing video data, a plurality of video data items are read in a timesharing fashion to be temporarily stored in a magnetic disk device or a semiconductor memory, thereby delivering the video data items therefrom to the users.

摘要:
A document processing system for processing documents by using structured keywords comprises an output system and a receiver system. The output system includes a first storage for storing a structured keyword dictionary containing structured keywords among which relations are systematically structured, and linkage unit providing linkage information for establishing correspondences between constituent parts of an input document and corresponding ones of the keywords. The receiver system is coupled to the output system and includes a second storage for storing structured keywords among which relations are systematically structured, and retrieving unit having inputs supplied with the document and the linkage information for retrieving the document to thereby form data of a predetermined edition format by using the structured keyword read out from the second storage. Data transfer between the output system and the receiver systems can be performed either on-line or off-line.

In a first embodiment of a CAM (Content Addressable Memory) or cache memory of the present invention disclosed herein, comparing information stored in a memory cell with comparison input information is accomplished in a comparison circuit without first converting a readout current from the memory cell into voltage information. In another embodiment, a matching detection between first stored information outputted from a first memory cell array and second stored information outputted from a second memory cell array is accomplished by an integrally formed sensing and matching detection circuit which is characterized as having both sensing and matching detection capabilities. That is, the sensing and matching detection circuit senses both stored information and thereafter detects matching based on a sensing result.

A computer system having a plurality of computers connected to each other by a computer coupling mechanism. Each computer includes a processor, memory, I/O device, disk control mechanism, computer coupling network adapter, disk requirement processing section connected to a system bus, and a disk connected to a disk control mechanism. The disk requirement processing section controls the disk, in response to a processing requirement for the disk from one of the processors of the other computers, based on structural definition information. The structural definition information describes a structure of the computer system. The computer system may be a loosely-coupled computer system.
摘要:
The timing of digital signal sampling at a receiver is continuously adjusted relative to a master clock used to initiate sending, by controlling a phase difference between the receiver sampling clock and the master clock in accordance with feedback of an error signal determined by detecting deviation of sampling clock timing from desired reference timing during both start-up operation and normal operation. Propagation delay scattering in the individual devices is compensated for by setting the sampling clock at a desired reference timing at start-up. Propagation delay scattering caused by fluctuation during device operation is compensated for by detecting the deviation of the sampling clock timing from reference timing based on received digital signals during normal operation and then continuously correcting the sampling clock timing on the basis of the detection result.
摘要:
A data communication system for a computer system in which computers are mutually connected includes: each computer having an area to store a command to execute data communication on the basis of it and a buffer area to store data; a switch circuit to mutually selectively connect the computers; and a transmission permitting component, connected between the switch circuit and one of the computers, for outputting a signal to permit the data transmission from one computer to another computer; a communication component for transmitting the data received from one computer by outputting the transmission permission signal from the transmission permitting component to another computer through the switch circuit; a detecting component to detect the occurrence of an abnormality regarding the data communication from one computer to another computer; and a communication control component to abandon the data that is subsequently received from one computer by outputting the transmission permission signal in accordance with an output of the detecting component. When the abnormality occurs, the switch circuit releases another computer, thereby disconnecting one computer and another computer. When reception commands prepared in the buffer area of another computer are perfectly used, another computer abandons the packet which does not include the flag to instruct the continuous reception.
