    Abstract: A memory monitoring method and a computing system. The computing system includes a processor, a memory and a monitor. The monitor obtains memory unit access information and process information of the computer system. The memory unit access information includes the number of access times of each memory unit of the memory. The process information includes information about a mapping relationship between a virtual address and a physical address of each memory units accessed by the current running process. After generating monitoring information, which includes the frequency at which the current running process accesses each memory unit, according to the memory unit access information and the process information, the monitor feeds the monitoring information back to the processor. Thus, the processor can perform memory management according to the monitoring information.

    Abstract: A method for accessing an extended memory, a device, and a system are disclosed. According to the method, after receiving a first memory access requests from a processor system in a computer, an extended memory controller sends a read request for obtaining to-be-accessed data to the extended memory and return, to the processor system, a first response message indicating the to-be-accessed data has not been obtained. The extended memory controller writes the to-be-accessed data into a data buffer after receiving the to-be-accessed data returned by the extended memory. After receiving, from the processor system, a second memory access request comprising a second access address, the extended memory controller returns, to the processor system, the to-be-accessed data in the data buffer in response to the second memory access request, wherein the second access address is different from the first access address and points to the physical address of the to-be-accessed data.

    Abstract: A first level buffer chip gates a target second level buffer chip according to a preset mapping relationship, a first chip select signal, and a first higher-order address signal, and forwards a memory access instruction and a lower-order address signal received from a memory controller to the target second level buffer chip. The target second level buffer chip determines a target memory module according to a second chip select signal and a delayed address signal obtained by delay processing on a second higher-order address signal, determines a target memory chip according to the lower-order address signal, acquires target data from the target memory chip according to the memory access instruction, and returns the target data to the memory controller. A cascading manner of a system memory is changed to a tree-like topological form, which avoids a protocol conversion problem and reduces the memory access time.
