Arithmetic processing device, information processing apparatus, and method for controlling arithmetic processing device

An information processing apparatus comprising:

• an arithmetic processing device;
• and
• a memory mechanism, wherein
• the memory mechanism has translation information that leads a second address from a first address, and
• the arithmetic processing device includes
• an arithmetic operation control unit,
• a first access management unit that receives an access request with respect to the first address and access authorization assigned to the access request from the arithmetic operation control unit, that translates the first address to the second address based on association information indicating an association relationship between the first address and the second address, that determines the suitability of the access authorization, and that outputs, when the access authorization is not suitable, the access request with respect to the first address, and
• a second access management unit that receives the access request with respect to the first address output from the first access management unit, that acquires the second address from the first address based on the translation information included in the memory mechanism, that determines the suitability of the access authorization, and that outputs, when the access authorization is not suitable, a notification of access prohibition to the arithmetic operation control unit.

A method for controlling an arithmetic processing device that includes an arithmetic operation control device, a first access management device, and a second access management device, the method for controlling the arithmetic processing device comprising:

• receiving, performed by the first access management device, an access request with respect to a first address and access authorization assigned to the access request from the arithmetic operation control device;
• translating, performed by the first access management device, the first address to a second address;
• determining, performed by the first access management device, the suitability of the access authorization;
• outputting, performed by the first access management device, when the access authorization is not suitable, the access request with respect to the first address to the second access management device;
• receiving, performed by the second access management device, the access request with respect to the first address from the first access management device;
• translating, performed by the second access management device, the first address to the second address;
• determining, performed by the second access management device, the suitability of the access authorization;
• and
• outputting, performed by the second access management device, when the access authorization is not suitable, a notification of access prohibition to the arithmetic operation control device.
