摘要:
An information processing system including an arithmetic unit in which one unit of data is processed according to a corresponding one instruction, and another arithmetic unit in which a great amount of data are processed according to a corresponding instruction. Also included is an instruction controller which distributes instructions selectively to respective arithmetic units (12) and a main storage (12) which achieves two-way data communication with the arithmetic units. In the system synchronization is performed with respect to instructions, among the aforesaid instructions, which, above all, must be executed in respective fixed execution sequences, by utilizing a newly employed synchronization instruction. Further, the aforesaid instructions are classified, in dependence upon the execution sequence, into first instructions which are to be executed under a serial processing mode and second instructions which can be executed under a parallel processing mode, by inserting both a serialized-starting instruction (POST) and a serialized-releasing instruction into the aforesaid instructions.

A memory access control system in a vector processing system comprises a memory unit, a memory device, address holding registers, a shift register and data buffer registers. The memory access control system distinguishes each vector data read out from the memory unit based upon the address holding registers by the output of the shift register. The shift register stores vector element numbers indicated by the memory device and transfers same to the data buffer registers. Each number from 0 to n-1, of a vector A composed of n elements a.sub.0, a.sub.1, a.sub.2, . . . a.sub.n-1, is a vector element number and each data, from a.sub.0 to a.sub.n-1, is vector element data.

A system for controlling the addition of signed binary numbers represented with N bits, of the 2's complement notation, is disclosed which includes addend and augend sign control circuits, and an adder circuit comprising a carry save adder and a carry proper gate adder. The addend sign control circuit receives an operation command sign signal (B, --B, .vertline.B.vertline. or --.vertline.B.vertline.) for the addend, which designates the addend of the certain type (B, .vertline.B.vertline. or --.vertline.--B.vertline.) to be applied directly to the carry save adder and designates the addend of another type (--B, .vertline.--B.vertline. or --.vertline.B.vertline.) to be applied to the carry save adder through a 1's complementer. The augend sign control circuit functions similarly for the augend being applied to the carry save adder. A corrective number (0, 1 or 2) is applied to the adder circuit which corresponds to neither, one, or both the addend and augend being applied to the adder circuit through their respective 1's complementer.

The present invention provides a gate apparatus for injection molding, that enables injection-molding moldings having a relatively small height and forming a plurality of cavities in an associated injection-molding die, the number of the cavities being greater than that of the cavities of the conventional injection-molding die of the same size. The gate assembly comprises an injection-molding die having a female die provided with a cavity, a down gate having an upper cylindrical portion, a middle taper portion and a lower small cylindrical hole formed in the lower end of the middle taper portion, and a cross gate formed through a wall separating the cavity and the lower small cylindrical hole; and a nozzle chip having a lower taper portion of a shape conforming to the middle taper portion of the down gate. The nozzle chip is provided with an axial projection axially projecting from the lower end of the lower taper portion, and a conical projection laterally projecting from the lower end of the axial projection. The nozzle chip is inserted in the down gate so that the conical projection is positioned near and opposite to the cross gate.

The present invention discloses a data processing system where a plurality of vector registers consisting of plurality of elements are provided between a main memory unit and an operational processing unit, the desired data is transferred to the vector registers from the main memory unit and is held therein, and various processings such as a logical operation are carried out by sequentially accessing the elements within said vector registers. The present invention also includes a plurality of memory banks which can be independently accessed and are provided for the vector registers. A series of elements of each vector register are interleaved in the plurality of memory banks and the elements having the same numbering in each vector register are arranged in the same memory bank. Timing necessary for starting access to a series of elements of said vector registers are specified for each class of processing, so that the vector operation processings can be done very effectively and without operand collision.

The present invention is provided for maintaining and replacing storage devices systematically in accordance with schedule. A storage control apparatus 1 has multiple storage devices 1A equipped with flash memory or the like. The storage control apparatus 1 monitors and records the utilization state of each storage device. When a storage device utilization state reaches a first threshold, the storage control apparatus starts an access control process to control the length of a maintenance period. When the storage device utilization state reaches a second threshold, the storage control apparatus executes blockage control, thereby causing this storage device to be replaced. The timing, at which a storage device with little lifetime remaining is replaced, is controlled to enhance maintenance work efficiency.
