Information processing terminal and information processing method

An information processing terminal comprising:

• an execution section containing a plurality of software pieces;
• a resource section including at least one resource to be accessed by at least one of the software pieces;
• a resource access section for mediating access by the software pieces in the execution section to the at least one resource by using a generic interface for accessing the resource section;
• a state of use determination section for determining whether the at least one resource is being currently used or not;
• an exploiting-software priority management section for managing a priority level of an exploiting-software piece, wherein the exploiting-software piece is a software piece currently using the at least one resource;
• a requesting-software priority acquisition section for acquiring a priority level of a requesting-software piece, wherein the requesting-software piece is a software piece which is making a request to access the at least one resource;
• and
• a conflict determination section for comparing the priority level acquired from the exploiting-software priority management section and the priority level acquired from the requesting-software priority acquisition section, and determining which one of the exploiting-software piece and the requesting-software piece should be granted access to the at least one resource,
• wherein, based on the result of the determination by the state of use determination section and the result of the determination by the conflict determination section, the resource access section is operable to:
• (A) if the at least one resource is not being currently used, or if the priority level of the requesting-software piece is higher than the priority level of the exploiting-software piece, access the at least one resource in accordance with the request of the requesting-software piece, and notify an error to the exploiting-software piece, or
• (B) if the priority level of the requesting-software piece is lower than the priority level of the exploiting-software piece, notify an error to the requesting-software piece.
