摘要： PROBLEM TO BE SOLVED: To improve transfer efficiency in transferring data to a common bus.
SOLUTION: An arbitration device holds a changeover time to be required for changing-over right to access to the common bus among a plurality of DSPs, and obtains the respective phase shift values of a plurality of DSPs, based on the change-over time and temperature information of the DSPs, which is received when the temperature of the DSPs is equal to or higher than a prescribed threshold, and then, generates and outputs different clocks by each DSP through the use of a reference clock transmitted by an oscillator and the obtained phase shift values.

摘要： PROBLEM TO BE SOLVED: To eliminate the need for wavelength selecting regulation on a subscriber's premise side while the same capacity of transmission is secured in an up link and a down link with a coated optical fiber, in an optical subscriber network in which two-way communication is done between an office device and a plurality of subscriber's premise with an optical signal of wavelength division multiplex.
SOLUTION: The office device transmits as down signals first optical signals of a plurality of wavelengths belonging to a first wavelength band containing data for transmitting to each subscriber's premise, second optical signals of a plurality of wavelengths belonging to a second wavelength band for generating an up signal, and third signals for excitation light. An array wave-guiding diffraction grating part branching the down signals from the office device transmits only signals allocated to each subscriber's premise out of the first and the second optical signals, and output them together with the third optical signals to each subscriber's premise. Each optical line terminating device of subscriber's premise is constituted so as to generate a wavelength for the up signal by extracting the signal in the first wavelength band and that in the second wavelength band with a filter.

摘要： PROBLEM TO BE SOLVED: To obtain an interruption control system which has simple configuration and is inexpensive even when the number of processors is increased by setting a control condition to an interrupt control register and performing interruption to a processor that is an object to be controlled with the interrupt control register. SOLUTION: An interrupt controller 200 receives an interruption request from plural input-output devices and sends it to a processor 101, and a host processor sets control conditions to an interruption control register 300. The register 300 performs interruption control, e.g. over a processor 102 that is an object to be controlled. Thus, in a multiprocessor system consisting of plural processors 101 to 10n, the register 300 controls interruption requests to all of the processors 101 to 10n. Therefore, there is no need to provide an interruption controller 200 for the processors 101 to 10n, and it is possible to simplify the configuration of the multiprocessor system and to reduce costs.
