Abstract

Perfeccionamientos en sistemas para liberar automáticamente un estado de bloqueo en un sistema de proceso de datos, en el cual una pluralidad de clases de funciones ocupan comúnmente una pluralidad de recursos, caracterizados porque el sistema comprende una posición de almacenamiento de tabla de control de funciones en espera que almacena la información concerniente a una función que se encuentra en estado de espera debido a una ocupación de un recurso por una cierta función, y una parte de memoria tampón de datos antes de imagen que almacenan los datos ante de imagen cada vez que se modifica el contenido del recurso, y cuando se genera el estado de espera con respecto a una primera función, el sistema examina el estado de espera de las demás funciones de acuerdo con el contenido de la parte de almacenamiento de la tabla de control de funciones en espera y el sistema juzga si el estado de espera de dichas otras funciones se debe a la ocupación del recurso por la primera función o no, y cuando el estado de espera de las otras funciones se debe a la ocupación de recurso por la primera función, el sistema libera la ocupación del recurso por la primera función, el sistema lleva a cabo el proceso de las otras funciones de acuerdo con el contenido de la parte de memoria tampón de datos antes de imagen, y después el sistema lleva a cabo el proceso de la primera función.
