Heterogeneous memory allocation method and device and electronic equipment

Abstract

The invention relates to a heterogeneous memory allocation method and device and electronic equipment, the heterogeneous memory comprises a plurality of nonvolatile memories, and the method comprises the following steps: receiving a memory allocation request initiated by an application program, reading memory resource information of a system, wherein the memory resource information comprises the memory size, the initial address, the current written frequency, the maximum writable frequency, the read delay, the write delay and the economic cost of the plurality of non-volatile memories; calculating the allocation cost of each nonvolatile memory in the plurality of nonvolatile memories based on the memory allocation request, the memory resource information and a preset calculation rule; and allocating the memories to the application program according to the allocation cost of the plurality of blocks of nonvolatile memories in an ascending order. According to the scheme, a more reasonable memory allocation optimization mechanism is provided and is used for balancing the write-in life loss and the read-write delay of the nonvolatile memory, so that the cost of each time of memory allocation is lowest.

Description

technical field [0001] The present disclosure relates to the technical field of memory management, and in particular, to a heterogeneous memory allocation method, device and electronic equipment. Background technique [0002] Non-volatile memory is a memory whose data will not be lost when the computer is turned off or suddenly or accidentally turned off. Therefore, non-volatile memory is generally used to store data. In the industry, computer storage is usually divided into three levels of storage structures based on storage capacity and access speed standards: CPU cache, internal memory, and external storage. Non-volatile storage generally corresponds to external storage. Specific product categories include tape, flash memory, Mechanical hard drives, solid state drives, etc. [0003] In recent years, with the rapid development of storage technology, non-volatile storage technology has also begun to exert force at the memory level. Intel officially released the first comm...

AI Technical Summary

Problems solved by technology

In view of this feature, the previous design will show relatively large shortcomings, which can be specifically manifested in: because the read operation is transferred to the non-volatile memory, and the read delay of the non-volatile memory is relatively high under actual conditions, so this operation Although it can reduce the loss of hardware to a certain extent, it will increase the delay of the program
