Computing circuit with stable power consumption and control method thereof

The embodiment of the invention discloses a calculation circuit with stable power consumption and a control method thereof, which are used for converting latched data in response to the situation that reduced power consumption is greater than a preset threshold value, and maintaining the calculation of the calculation circuit based on the converted data so as to maintain the power consumption stability of the calculation circuit. Therefore, the problem of jitter of electric signals such as current and voltage caused by excessive reduction of power consumption of the calculation circuit can be avoided, and the stability of a chip is improved. 本发明实施例公开了一种功耗稳定的计算电路及其控制方法，响应于降低的功耗大于预设阈值，对锁存的数据进行变换，并基于变换后的数据维持计算电路的计算，以维持计算电路的功耗稳定性。由此，可以避免计算电路的功耗下降过大时导致的电流和电压等电信号抖动的问题，提高了芯片的稳定性。
