Abstract
SE PREVE UN CIRCUITO DE MICROPROCESADOR QUE PERMITE QUE LA VELOCIDAD DEL RELOJ DE MICROPROCESADOR INTERNO VARIE DEPENDIENDO DE UN REGISTRO QUE PUEDE SER PROGRAMADO POR PROGRAMA INFORMATICO. ADEMAS, EL CAMPO DE TRANSMISION DEL GENERADOR DE RELOJ INTERNO PUEDE SER VARIADO DE MANERA SIMILAR POR PROGRAMACION INFORMATICA. EL PROGRAMADOR O USUARIO DEL MICROPROCESADOR PUEDE CAMBIAR LA VELOCIDAD DE RELOJ INTERNO DE MANERA QUE EL MICROPROCESADOR OPERA EN UNA PRIMERA FRECUENCIA O EN UNA SEGUNDA FRECUENCIA DEPENDIENDO DE LOS REQUISITOS DE PRESTACION. UNA FRECUENCIA MAS BAJA DE OPERACION PUEDE SER ELEGIDA PARA UN CONSUMO DE ENERGIA BAJO Y EMI BAJO, MIENTRAS QUE UNA FRECUENCIA MAS ALTA DE OPERACION PUEDE SER ELEGIDA PARA APLICACIONES DE GRANDES PRESTACIONES E INTENSIVAS DE CALCULO.
