Abstract
La presente invención se refiere a un sistema de computadora que incluye un microprocesador, dicho microprocesador exhibiendo una entrada de reajuste y contando, además, con una entrada de reloj a la cual se suministra una entrada de reloj, dicho sistema teniendo la capacidad de generar una señal de reajuste del microprocesador, un circuito de reajuste del microprocesador que comprende: un medio de detección de error de fase para detectar un error de fase entre dicha señal de reloj y dicha señal de reajuste; un medio de corrección de error de fase, acoplado a dicho medio de detección de error de fase, para ajustar la fase dicha señal de reloj si se detecta un error de fase de tal manera que se reduzca al mínimo dicho error de fase, y un medio de regeneración de la señal de reajuste para suministrar una nueva señal de reajuste a la entrada de reajuste de dicho microprocesador cada vez que la fase de dicha señal de reloj sea ajustada.
