Abstract: The present disclosure provides a method and apparatus for parsing contiguous system addresses, and an electronic device. The method for parsing contiguous system addresses comprises: acquiring system level information upon receiving contiguous system addresses; acquiring logical address ranges of objects in a first level based on the contiguous system addresses and the system level information; and when successively acquiring logical address ranges of objects in a second level, . . . , or an Nth level of the system, acquiring logical address ranges of objects in a present level based on a logical address range of a previous level and the system level information, wherein N is the number of levels, and N is an integer greater than or equal to 2, and a logical address range of an object comprises a start address and an end address of the object.

Abstract: A method for controlling an application to access a memory includes: receiving a first access request provided by the application and having a first access key; verifying the first access key; generating a second access key for the application if the verification of the first access key is successful; storing the second access key and providing the second access key to the application; receiving a second access request provided by the application and having a target address and a second access key; identifying whether the target address is within a reference address space indicative of a preset storage location of the memory, and verifying the second access key; generating an access control command according to an identification result of whether the target address is within the reference address space and a verification result of the second access key received from the application so as to restrict or permit the application to access the memory.
