Abstract:
Memory space management and memory access control method and apparatus are provided. The method includes: upon receiving an access request, acquiring an access address and an accessor identifier in the access request; checking a current state of a memory space pointed by the access address to obtain a check result, wherein the state of the memory space includes a first state and a second state; determining whether the accessor identifier belongs to an access permission set among a plurality of access permission sets that corresponds to the check result; and generating an instruction according to the check result, wherein the instruction indicates whether or not the accessor is permitted to access the memory space. With the above method, the invention reduces resource waste and system costs.

Claim (Index 8):
The method according to  claim 7  wherein the step of generating the instruction according to the search result comprises:\n when the memory space belongs to the security memory region, if the accessor is in the security state, generating the instruction permitting the accessor to access the memory space, otherwise generating the instruction not permitting the accessor to access the memory space; \n when the memory space belongs to the non-security memory space, regardless of whether the accessor is in the security state or the non-security state, generating the instruction permitting the accessor to access the memory space; alternatively, when the accessor is in the non-security state, generating the instruction permitting the accessor to access the memory space, otherwise generating the instruction not permitting the accessor to access the memory space.
