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 4):
The method according to  claim 1 , further comprising:\n if the operation requested by the hardware unit is not accessing the security memory region in the system memory, changing at least a part of the non-security memory region in the system memory from the first state to the second state, and setting the hardware unit to a non-security state; wherein, when the non-security memory region is in the first state, it means that the non-security memory region is permitted to be accessed only by the processor; when the non-security memory region is in the second state, it means that the non-security memory region is permitted to be accessed by the hardware unit in the security state or in the non-security state, or permitted to be accessed only by the hardware unit in the non-security state.
