可降低耗电量的内含多个振荡器的装置与其相关方法
摘要：
本发明提供一种可降低耗电量的内含多个振荡器的装置，其包含第一振荡器、第一计数器、第二振荡器、第二计数器以及处理器。第一计数器耦合于第一振荡器，用来计数第一振荡器所产生的信号的周期以产生第一振荡器的周期数；第二计数器耦合于第二振荡器，用来计数第二振荡器所产生的信号的周期以产生第二振荡器的周期数；以及处理器耦合于第一计数器和第二计数器，用来依据第二振荡器的周期数确定方程式以模型化第一振荡器的周期数，并利用方程式和第二振荡器的目前周期数来获得第一振荡器的预期目前周期数。本发明所提供的装置可降低功率消耗，延长电池寿命，并大幅降低第一振荡器的时间不确定因素，提升了接收器的接收性能。
摘要（英）：

The present invention provides a device with a plurality of oscillators capable of reducing power consumption, including a first oscillator, a first counter, a second oscillator, a second counter and a processor. The first counter is coupled to the first oscillator, for counting the cycle of signal generated by the first oscillator, to generate a cycle number of the first oscillator; the second counter is coupled to the second oscillator, for counting the period of signal generated by the second oscillator, to generate a cycle number of the second oscillator; and the processor is coupled to the first counter and the second counter, to determine an equation based on the cycle number of the second oscillator to model the cycle number of the first oscillator, and to obtain the anticipated present cycle number according to the equation and a current cycle number of the second oscillator. The device of the invention can reduce power consumption, prolongs battery lifetime, and reduce the time indeterminacy element of the first oscillator and improve the reception performance of the receiver.
