Abstract: A store control method for a computer system having a storage with independently accessible plural store banks, plural access request controllers for issuing access requests to the storage, and a store controller for transmitting the access requests to each store bank. The store controller has an access request priority determining circuit of plural stages for selecting the access requests in the order of higher priority for each store bank so as to determine the order of priority between the access requests in multiple stages on the basis of the access requests. Further, plural priority control circuits of each stage are provided for stepwise performing control of priority of the main store access requests issued by the vector data processor for each of the store banks. Access is made to the main storage by assuring the order between the vector elements constituting vector data by allowing each first priority control circuit to send the access requests to the priority control circuit of next stage.

Abstract: A data processor having memory requesters to execute instructions, an instruction hold unit disposed for each resource to hold an instruction being executed in the resource and instructions to be executed therein, and execution control units to cause, in a case where an execution completion report of an instruction being executed in either one of the resources is received, an instruction held in an instruction hold unit corresponding to the resource to be immediately executed, thereby successively supplying the respective resources with data items to be employed for executions of the consecutive instructions in the resources.

Abstract: A plurality of storage control units are employed in the storage control unit section; moreover, two requester modules are adopted in association with these storage control units. Each memory module is constituted with as many access bank groups as there are storage control units. The access bank groups operate in concurrent fashion and are accessible from any one of the storage control units. In the element assignment, a plurality of request control units in each requester module and a plurality of vector data controllers in each vector register unit are respectively assigned with serial numbers beginning from zero. For a vector data controller, a number assigned thereto is divided by the request module count to attain a remainder such that the vector data controller is assigned to a request module having a number identical to the value of the remainder.

Abstract: A storage control apparatus of a computer system having a plurality of transfer pipelines issuing access requests to a plurality of memory banks of a storage device. Each memory bank is independently accessible in response to an access instruction from a vector processing device. Each of the transfer pipelines includes a plurality of access request control devices to which the access instruction from the vector processing device is allocated in association with elements of a vector. The access request control devices simultaneously issue in response to an access instruction a plurality of access requests. Each transfer pipeline also includes a priority decision device which detects whether or not the access requests forecasted to be issued from the plural access request control devices contend with the access requests issued from the plural access request control devices of another transfer pipeline.

Abstract: Frames of digital data each representing a single picture of a video motion picture display are handled in a computer system with an extended memory operating in parallel with a computer system instruction processor and main memory to bypass the computer system input/output processor for continuously outputting the video information on a real time basis. The outputted data may be recorded continuously at a constant data rate for an entire motion picture worth of information or actually displayed on the video display on a real time basis. The extended storage has a memory larger than the main memory, where all of the frame data is stored and read out in high speed bursts to a buffer that continuously reads the data out of the buffer for outputting.
