Abstract
The present invention discloses a method for external devices accessing computer memory, which includes: the external device applying to a computer for a memory space with a certain size, and receiving multiple memory blocks fed back by the computer; the external device establishing a memory mapping relation between the external device and the computer by means of a sequential storage structure or a chain storage structure; and when initiating a read-and-write operation, the external device finding the corresponding offset address in said computer according to the memory mapping relation between the external device and the computer, generating a read-and-write burst command, and actualizing read-and-write operations in the computer memory. The present invention can achieve the rapid and continuous access to multiple discontinuous memory areas of the computer memory, and improve the speed in the computer's operating system and external devices accessing the memory.
