The mapping module is used for mapping out corresponding user address space information according to the physical address space information acquired by the acquisition module;
The reading module is used for reading the user address space in the user address space information mapped by the mapping module;
the access module is used for accessing the user address space read by the reading module by the AVS2 encoding application program;
Wherein the mapping module is further configured to:
Responding to a first mapping request of the AVS2 encoding application program, wherein the first mapping request is used for mapping out a physical address space in the physical address space information, and mapping out the physical address space through an address mapping driver;
Responding to a second mapping request of the AVS2 encoding application program, wherein the second mapping request is used for mapping out a user address space corresponding to the physical address space, and mapping the physical address space to the user address space through the address mapping driver;
the address mapping driver includes a first driver mapping out of the physical address space, an
A second driver that maps the physical address space to the user address space.
