TEMPERATURSTEUERUNGSVORRICHTUNG EINER ZENTRALEN VERARBEITUNGSEINHEIT |
摘要 |
The invention concerns a device (48) for thermal control of a central processing unit (CPU) (17) having a plurality of operating frequencies. The device (48) comprises a thermal sensor (51) connected to the CPU (17) to detect the temperature thereof and to generate a resulting analog signal which is amplified by an amplifier (52) and converted into a digital signal by an analog/digital conversion stage (53). A comparator circuit (55) compares the digital signal to a predetermined temperature value stored in a memory (54) and generates an interrupt signal (SI) when the compared values are equal. The signal (SI), by means of a circuit (61) for division of the frequency of the timing signal (CK) generated by an oscillator (61), causes a reduction in the operating frequency (FO) of the CPU (17). |
