Filed: 1979-02-28
Abstract: PURPOSE: To obtain a fault supervisory system which does not require any special control bus by sending fixed data from a supervisory unit to processors via a signal bus at constant intervals, and then by discriminating sent-back data from respective processors.  
     CONSTITUTION: Between supervisory unit SP and processors P 0 , P 1 ...P n , data of a special pattern are transferred at constant intervals via signal bus BUS. As for data patterns, there are two kinds of patterns, a pattern of which a processor when receiving data A from unit SP sends back the received signal A as it is to unit SP and that of which the processor sends back data B received from unit SP to unit SP by converting to data C. Unit SP sends two patterns in the order of processors P 0 →P 1 ...P n →P 0 →P 1  and when the sent-back data is any othe one than A and C, the processor is judged to be abnormal to display that on fault information display unit DSP.

IPC: H03M1/50
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To execute a parallel arithmetic operation by a large-scaled input signal with a few elements and low energy consumption by integrating current pulses generated corresponding to an outside input signal, and converting them into charges, converting the amounts of the integrated charges into a binary digital signal, and outputting it. SOLUTION: A pulse width modulation(PWM) signal 1 is inputted to a switched current source 2, and constant currents are generated only in a pulse width time, and converted into current pulses. The (n) pieces of current pulses are overlapped on a common current bus 3, and full charge amounts in proportion to the total sum of the input pulse width are obtained by a capacity integration method by a reference charge counting circuit(CPC1 ) 6. Excess charges generated as a quantization error are digitized on a time axis by a charge/time converting circuit(CTC) 7 so that the time resolution of the arithmetic operation is improved. Those digitized values are weighted and added in a digital area by using digital counter circuits 8 and 9, and outputted as a binary digital signal as the added result of the PWM signal 1.
