Information processing apparatus and method of updating stack pointer
摘要:
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.
