Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, further detailed descriptions provided in the embodiments according to the present invention will be provided below in conjunction with the accompanying drawings.

[0029] In recent years, with the development of storage technology, many new types of non-volatile memory have appeared, and their performance has been greatly improved, whether in terms of non-volatility or energy consumption, or access speed or scalability. Great progress, the read and write speed of some non-volatile memories can reach the nanosecond level, even comparable to the read and write speed of DRAM memory, and it is more power-saving and storage dense than traditional DRAM memory, and has Anti-radiation interference and other advantages.

[0030] The inventor has made full use of the characteristics of the non-volatile memory that can store data for a long time in the case of power failure, and adopt...

Abstract

The invention relates to a nonvolatile computation device. The nonvolatile computation device comprises a processing unit and an off-chip storage unit, wherein the processing unit comprises a centralprocessing unit and an on-chip storage unit; the off-chip storage unit comprises a nonvolatile storage device; and the on-chip storage unit comprises a nonvolatile storage device and a volatile storage device.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a non-volatile computing device and a working method thereof. Background technique [0002] Generally speaking, according to the storability of information, memory can be divided into volatile memory and non-volatile memory, wherein the data in volatile memory will disappear after power off, such as static random access memory or dynamic random access memory Memory, etc., the data in the non-volatile memory will not disappear after being disconnected, such as flash memory or hard disk. [0003] Generally, compared with non-volatile memory, volatile memory has fast read and write speed but is expensive. Therefore, in computing devices, non-volatile memory is generally used as off-chip memory, such as tape, disk or flash memory; The on-chip memory generally adopts volatile memory, such as cache or memory. Since the data in the volatile memory cannot be saved after power failure...
