    摘要: A FIFO memory using one of the ports of a RAM having two or more ports for writing and another port for reading is disclosed. Writing into the FIFO memory is done instantly, while reading from the FIFO memory is effected by holding the output of the preliminarily accessed RAM until the end of a reading operation. The output of the RAM is updated by a request from outside and according to the state of the FIFO memory, and this operation is done simultaneously with reading or writing.

    摘要: In order to prevent destruction of a read gate by excessive storage of charge without any addition or change to the manufacturing process, the array type X-ray detection apparatus using a direct conversion system, which directly converts irradiation X-rays to charge, provides each pixel cell with a sensor section for converting X-rays to an amount of charge according to the amount of X-rays, a charge collecting electrode for storing the charge generated, a read gate for transferring the stored charge to an external read amplifier and a MIS diode using a TFT. A clamp signal is applied to one end of the MIS diode. The read gate and MIS diode are formed in the same manufacturing process. Since the amount of charge stored in the charge collecting electrode is clamped to the amount of charge corresponding to the clamp signal voltage by the MIS diode, the read gate is not destroyed even with excessive X-ray irradiation. Furthermore, instead of the MIS diode, a cutoff voltage control circuit and a cutoff gate using a TFT connected to the cutoff voltage control circuit are provided. When the output of the charge storage capacitor exceeds a cutoff voltage, the cutoff gate interrupts the inflow of charge to the charge storage capacitor to suppress further increase of output, thus preventing the read gate from being destroyed.

    摘要: One block of non-zero coefficients obtained through the decoding of the entropy decoding unit 2024 is stored in the coefficient storage unit 121 in accordance with positional coordinates calculated by the non-zero coefficient scanning order calculation unit 2023a and the non-zero coefficient position conversion unit 2023b. The stored non-zero coefficients are then inverse quantized by the inverse quantization unit 2022. The non-zero coefficient range calculation unit 122 specifies a region of the coefficient storage unit 121 in which the non-zero coefficients are stored. The calculation order control unit 123 controls the inverse DCT unit 2021 to only perform an inverse DCT (discrete cosine transform) for non-zero coefficients located in the specified region.

    摘要: In each processing device of a parallel processor system, a processor outputs a signal when all the transmit data are transmitted to a router. A latch receives the signal from the processor to output a signal set to HIGH. To an AND gate are inputted the signal set to HIGH outputted from the latch and a signal set to HIGH which indicates that the router has no receive data received from a network. The parallel processor system performs AND operation on the outputs of the AND gates of all the processing devices, and detects that a data transmit/receive processing is completed among all the processing devices according to the results of AND operation.

    摘要: In a data transmission device, before the starting of data transmission, a data conduct device detects an external bus, and an address comparator section compares the value of the address signal line with the output values of the parameter memory section. As the result of the comparison, when it is judged that the data to be transmitted is present on the external bus, the address comparator section transmits a write-execution signal to a bus control unit so that the bus control unit writes the data present on the external bus together with the validity bit thereof into the data memory device. In the period of data transmission, when the data assigned to the address produced by an address generator is present in the data memory device, the data is transmitted to the external destination, and on the other hand, when the data assigned to the address is absent in the data memory device, the bus control unit gains access to the external memory for obtaining the data corresponding to the address, so that the data obtained from the external memory is transmitted to the external destination.
