Abstract

LA INVENCION DESCRIBE UN CONTROL DE ACCESO A MEMORIA PARA MICROCONTROLADOR ACOPLADO PROGRAMADO POR MASCARA, EN PARTICULAR EN APLICACIONES PARA CONTROLADORES PROGRAMABLES EN MEMORIA, EN LA ZONA DE BAJO COSTE. EL ACOPLAMIENTO DE LOS MICROCONTROLADORES (MC1, MC2) Y SU AUTORIZACION PARA ACCESO A LA MEMORIA SOBRE LAS MEMORIAS EXTERNAS DEL PROGRAMA Y DE DATOS (7), SE BASA EN UNA CONEXION DEL CABLEADO DEL HARDWARE EN COMBINACION CON UN ESTABLECIMIENTO DE ENLACE CONFORME AL SOFTWARE. SIEMPRE ACCEDE SOLO UN MICROCONTROLADOR A LAS MEMORIAS EXTERNAS DEL PROGRAMA Y DE DATOS (7), MIENTRAS QUE EL OTRO U OTROS MICROCONTROLADORES ACCEDEN A SU MEMORIA DE PROGRAMA INTERNO. EL ACCESO A LA MEMORIA SE COORDINA POR EL MICROCONTROLADOR QUE TRABAJA COMO MAESTRO (MC1) POR MEDIO DE SU PUERTO DE SALIDA (PX.Y). CONFORME AL HARDWARE SE MULTIPLEXA LA SEÑAL DE ACCESO A LA MEMORIA (PSEN) Y LA SEÑAL DE ACCESO A LA DIRECCION (ALE) PARA EL MICROCONTROLADOR CON AUTORIZACION DE ACCESO. CON ELLO EL ACOPLAMIENTO CONFORME AL HARDWARE APROVECHA LOS PUERTOS DE ENTRADA/SALIDA (P0...P3) DE ACCIONAMIENTO BIDIRECCIONAL Y SU FUNCION ALTERNATIVA.
