Abstract

The embodiment of the invention discloses an access method, device and system for expanding memory. Among them, the method includes: receiving N+1 memory access requests serially sent by the processor system of the computer, the access addresses in each memory access request are different from each other and all point to the same physical address, and the physical address is the data to be accessed in the said The storage address on the extended memory, N≥1 and N is an integer; when receiving the first memory access request, send a read request to the extended memory, and return a specific response message to the processor; In the process of accessing data, each time a memory access request is received, a specific response message is returned to the processor within the delay specified by the memory bus protocol until the data to be accessed is written into the data buffer; after that, the data to be accessed is Return to the processor system.

Description

technical field [0001] The invention relates to the field of computers, in particular to an access method, device and system for expanding memory. Background technique [0002] The application of big data puts forward higher and higher requirements for computer processing capabilities. An important indicator of improving computer processing capabilities is the improvement of memory capacity. In one application scenario, under the condition of limited integration of existing memory chips, multiple memory chips are connected through expansion chips to achieve expansion of memory capacity. Another application scenario is that in more and more computer systems, application acceleration chips are added to accelerate processing of certain specific applications, such as GPU (Graphic Processing Unit, graphics processing unit) acceleration, which is used to This type of application acceleration chip can generally be implemented by using ASIC (Application Specific Integrated Circuit,...
