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 6):
A memory access control method, for controlling a system memory accessed by a processor or a hardware unit, comprising:\n upon receiving an access request, acquiring an access address and an identifier of an accessor 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 comprises a first state and a second state; looking up whether the identifier of the accessor belongs to an access permission set among a plurality of access permission lists that corresponds to the check result to generate a search result, wherein the plurality of access permission sets comprises a first access permission list corresponding to the first state and a second access permission list corresponding to the second state; and generating an instruction according to the search result, wherein the instruction indicates whether or not the accessor is permitted to access the memory space.
