A data processor has sixteen processing elements that each include a register file and an arithmetic logic unit. A network unit connects between the register files of the processing elements and the arithmetic logic units of the processing elements. The network unit has a selector for simultaneously performing a plurality of data transfers which are each made from a register file of one processing element to an operation unit of another processing element. With the provision of this selector that can perform such simultaneous data transfers, the processing efficiency of the processing elements can be maintained even if a change occurs in operand assignments and the like.

To provide a thin wideband antenna unit capable of shrinking the size of a radiation element in a case where a dielectric is not used.In a wideband antenna unit 10 having a ground plate 12 and a flat shaped radiation element 14 disposed on a plane (x, y) flush with a plane where the ground plate extends, the radiation element 14 has an elliptically shape. The radiation element 14 and the ground plate 12 are apart from each other by a predetermined feeding distance ΔFD. A ratio between an outside diameter 2aout in an ellipse's x-direction and an outside diameter 2bout in an ellipse's y-direction is 8:5. The elliptically shaped radiation element 14 has an elliptically shaped opening 14a which is concentric O with the elliptically shape. An inside diameter 2bin in the ellipse's y-direction is half of an outside diameter 2bout in the ellipse's y-direction. It is desirable that an inside diameter 2ain of the elliptically shaped opening 14a in the ellipse's x-direction is not more than half of the outside diameter 2aout in the ellipse's x-direction.

An antenna unit consists of an EBG reflector, a single curl antenna supported at a central portion of the EBG reflector, and a periodic structure upper plate disposed apart from a principal surface of the EBG reflector by a predetermined distance. The EBG reflector includes a substrate having the principal surface and (Nx×Ny) square patches which are printed on the principle surface of the substrate and which are arranged in a matrix fashion (lattice structure). The periodic structure upper plate consists of a film and (Nx×Ny) square patch-like conductors printed on the film. The (Nx×Ny) square patch-like conductors are disposed so as to oppose to the (Nx×Ny) square patches, respectively.

Each of D flip-flops (FFs) 13a to 13f constituting a scan path circuit has a normal operation input circuit to be selected in a normal operation and a test operation input circuit to be selected in a test operation, and a control signal having an intermediate voltage between a supply voltage and a ground voltage is sent from a voltage generating circuit 17 to the test operation input circuit of each FF in the test operation. In this case, the amount of an output change in data in each FF is smoother than that in the case in which the supply voltage is applied. Consequently, the delay time of the data is increased. The intermediate voltage to be applied to each FF in the test operation is determined based on a feedback signal sent from a test circuit 15 for checking whether scanned-out data have an error or not.

An antenna device comprises a coaxial cable that has a central conductor and an outer conductor and is folded into an L-shape at an end portion. An L-shaped first-conductor-portion is electrically connected to the central conductor at the end portion of the coaxial cable. An L-shaped second-conductor-portion is electrically connected to the outer conductor at the end portion of the coaxial cable and is disposed along an outer circumferential face of the coaxial cable. The first and second conductor portions as a whole are formed into an approximate U-shape.

In order to feed at four points to a loop portion (12) made of conductor formed around a central axis (O) in a loop fashion along a peripheral surface of a cylindrical body (11) formed by rounding a flexible insulator film member (20) around the central axis in a cylindrical fashion, each of four feeders (13) formed on the peripheral surface of the cylindrical body comprises a vertical feeding portion (131) having one end (131a) grounded and another end (131b) extending toward the loop portion, a zigzag line (132) disposed between the other end of the vertical feeding portion and the loop portion, a tap (133) for feeding from a feeding terminal (13a) to the vertical feeding portion.
摘要:
A signal cache memory controller which includes line for inputting an index section of an address is formed with a branch line which is intervened by an address delay circuit. In each of banks X and Y, a switching circuit selects the data which has been delayed in response to a select signal Sse being outputted as a cache-access address to be outputted to a tag memory. An address comparator compares a tag section of the address input through a signal line for inputting the tag section with a reference address output from the tag memory and outputs an coincidence signal if there is a coincidence therebetween. When the coincidence signal is generated and the select signal Sse is not generated, a bank-hit signal generating circuit generated a bank-hit signal Sbh, in response to which a select-signal generating circuit generates the select signal Sse. The circuit for controlling a cache memory which is divided into a plurality of banks enables the writing of data in the cache in every cycle.
