Latest Patents

Igarashi's latest patents include a clock-signal generation device and a communication device. The clock-signal generation device is designed to change the average frequency of a clock signal independently of a reference clock signal. It features a reference-clock-signal generation circuit that produces a reference clock signal. A frequency-division circuit divides the frequency of this reference clock signal, generating a frequency-divided signal. The control circuit modifies this frequency-divided signal by inserting extension cycles at predetermined intervals, allowing for arbitrary setting of the average frequency of the clock signal. Additionally, the clock signal generator circuit utilizes a logical result from the output of a clock generator, which generates clock signals for a central processing unit and functional blocks. This innovation optimizes power consumption while ensuring the microcontroller system operates at the required minimum speed.
