Embodiment Construction
[0065] In order to make the purpose, technical solution and advantages of the present invention clearer, a memory access buffer device and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0066] A kind of memory access buffer device and method of the present invention, its basic principle is, at first cache the read request on the read channel, then send the read request longer than the original request length to the memory controller without wasting the effective bandwidth of DDR, if Before the read data is returned, if there is a new request on the read channel that falls within the relevant address of this access, then there is no need to send a read request to the memory controller, and only need to record the corresponding information...
