INFORMATION PROCESSOR

摘要

Provided is an information processor equipped with a virtual information processor implementation means that implements one or more virtual information processors by managing hardware resources; a data transmission means that transmits data directly from an input-output device that controls data input-output with an external device to the first memory area assigned to the virtual information processor, by converting an address in a first memory area assigned virtually to a virtual information processor to an address in a second memory area that is the real memory of the first memory area; a transmitted data detection means that detects data directly transmitted from the input-output device to the first memory area assigned to the virtual information processor; an update information registration means that generates update information pertaining to the first memory area which is modified by the data detected with the transmitted data detecting means, and stores the update information in an update information storage means; and an update information output means that outputs the update information stored with the update information storage means.
