Abstract: PROBLEM TO BE SOLVED: To execute fast analog arithmetic through the use of an analog voltage value by providing a pulse extracting means and an electric discharging means, etc., for discharging the current of an electric storing means while being fed back with the output of the pulse extracting means as a control means. SOLUTION: The pulse output of a pulse extracting part 13 is fed back as the control signal to turn on the third analog switch 140 of an electric charge discharging part 14. Thereby, the current of a capacitor 111 is discharged through an electric discharge adjusting part 141. This process continues until the voltage of the capacitor 111 becomes smaller than the reference voltage of a voltage comparator 121, and a pulse extraction part 13 outputs a pulse in the cycle of a master clock. Consequently, a voltage/pulse converter which is capable of fast analog arithmetic through the use of an analog voltage value in analog signal processing and analog/digital mix signal processing is obtained by changing a pulse by the voltage change of the capacitor 111.

Abstract: PROBLEM TO BE SOLVED: To provide the high-speed packet switch controller which is very suitable to a large-capacity packet switch controller and can maximize system performance through optimum switching by making use of the neural network chip. SOLUTION: A connection ring array 42 to which addresses generated by decoding a weighted value row address and a weighted value column address through a weighted value row address decoder 40 and a weighted value column address decoder 41 are inputted coupled an input signal to a neural network 43 according to the said address and also varies an output value according to an externally inputted weighted value. The neural network 43 outputs a crossbar switch control signal, generated by amplifying the signal outputted from the connection ring array 42, to the outside through an input/output bus 44.
