Taking the high precision on chip RTC as the time base control unit and using genetic algorithms to search the best OSCCAL register value, it will make the on chip RC oscillator generate a high precision clock for the MCU. This methord can be used fast and real time, so the CPU will get a stable clock source.

以AVR片内高精度时钟单元RTC为时基控制单元，以标准时间内MCU定时器的计数值为控制目标，采用遗传控制策略搜索对应MCU理想时钟频率的OSCCAL寄存器最佳设置值，快速、准确地对RC振荡频率进行校准，为CPU提供具有高抗干扰特性的精确时钟。
