Abstract

Abstract Translated from Japanese (57)【要約】 【目的】本発明は、CPUボードを実装する電子機器に 於いて、CPUチップの発熱温度を迅速かつ正確にチッ プの温度制御に反映させ、CPUチップのもつ性能を十 分に活かして、CPUチップを限界周波数付近で高速動 作できるようにしたことを特徴とする。 【構成】CPUチップ11にクロックを供給する回路1 3と、CPUチップ11に直付けされた温度センサ12 と、この温度センサ12の検知信号をもとに上記クロッ クの周波数を制御する回路13とを具備し、CPUチッ プ11に直付けされた温度センサ12の検知信号をもと にCPUチップ11に供給されるクロックの周波数を直 接制御することを特徴とする。 (57) [Summary] [Object] The present invention, in an electronic device having a CPU board mounted thereon, reflects the heat generation temperature of the CPU chip in the temperature control of the chip quickly and accurately, thereby sufficiently improving the performance of the CPU chip. The feature is that the CPU chip can be operated at high speed near the limit frequency by making full use of it. [Structure] Circuit 1 for supplying clock to CPU chip 11 3 and a temperature sensor 12 directly attached to the CPU chip 11. And a circuit 13 for controlling the frequency of the clock based on the detection signal of the temperature sensor 12, and supplies the CPU chip 11 with the detection signal of the temperature sensor 12 directly attached to the CPU chip 11. It is characterized in that the frequency of the clock to be controlled is directly controlled.
