Patent application number | Description | Published |
20090138963 | Information processing apparatus and method of controlling program execution of same - A CPU contained in an information processing apparatus in accordance an exemplary embodiment of the present invention outputs an access request including first access destination address information by a first program, and outputs a check request including second access destination address information when the execution program is switched from the first program to a second program as a result of a program call from the first program to the second program. A protection setting check portion contained in the information processing apparatus checks whether or not the check request including the second access destination address information conforms to protection setting for the first program based on memory protection information that is established in a memory protection information storage portion to detect a violation by a memory access request by the first program. | 05-28-2009 |
20090144465 | Data processing apparatus and method of protecting a peripheral device in data processing apparatus - A data processing apparatus includes an arithmetic circuit and a peripheral device protection circuit that controls access of the arithmetic circuit to the peripheral devices. The peripheral device protection circuit has a first protection preset value and a second protection preset value set as a protection level higher than that of the first protection preset value. The peripheral device protection circuit includes: a setting selection circuit that generates access permission/denial information by referring to the first protection preset value and the second protection preset value when the arithmetic circuit operates at a first operation authority level, or by referring to the second protection preset value when the arithmetic circuit operates at the second operation authority level. An access protection circuit that determines permission/denial of access to the peripheral devices based on access information output from the arithmetic circuit and the access permission/denial information. | 06-04-2009 |
20090172231 | Data processing device and bus access control method therein - A data processing device includes a computing circuit that accesses a peripheral device connected to through a internal bus, an internal bus connection circuit that is provided between the computing circuit and the internal bus, and switches an enable and a disable state of an access from the computing circuit to the internal bus, an exception notification controller that outputs an exception occurrence notification signal to the computing circuit based on an error occurred in the peripheral device, and a bus disablement controller that instructs the internal bus connection circuit to disable an access from the computing circuit to the internal bus in accordance with the notification of the exception occurrence notification signal, and instructs the internal bus connection circuit to cancel the disablement of the access in accordance with a start of an exception processing based on the exception occurrence notification signal. | 07-02-2009 |
20090172332 | Information processing apparatus and method of updating stack pointer - A instruction execution part of an information processing device outputs an access request including a first address information to specify an access destination based on an execution of an access command of an address space in a memory. The instruction execution part also outputs a check request including a second address information to specify a stack pointer point after extension based on an execution of a stack extension command to extend a stack included in the address space in the memory by updating a stack pointer. A protection violation detection section of the information processing device detects whether the access destination includes the plurality of the partial spaces by collating the first information with the memory protection information stored in the memory protection information storage section. | 07-02-2009 |
