The invention provides an SCM-based data processing method and device and a computer readable storage medium, and the method comprises the steps that a main processor unit executes a first instruction obtained from a random access memory unit, the first instruction is used for enabling the main processor unit to write preset data into a second storage area of a flash memory unit through a memory control unit, and the first instruction is mapped to the random access memory unit from a first storage area of the flash memory unit by the memory control unit; a coprocessor unit executes a second instruction acquired from the random access memory unit, and the second instruction is used for enabling the coprocessor unit to perform logical operation on preset data acquired from the second storage area and write a logical operation result into a third storage area of the flash memory unit through the memory control unit; and the second instruction is mapped to the random access memory unit from the fourth storage area of the flash memory unit by the memory control unit. The performance of the main processor unit and the coprocessor unit can be exerted to the maximum extent.
Description
technical field [0001] The present invention relates to the field of computer data processing, and more particularly, to an SCM-based data processing method, device and computer-readable storage medium. Background technique [0002] At present, DRAM (Dynamic Random Access Memory, dynamic random access memory) includes synchronous dynamic random access memory (SDRAM), double data rate (DDR) SDRAM, second generation double data rate (DDR2) SDRAM, third generation Various types, such as double data rate (DDR3) SDRAM and fourth-generation double data rate (DDR4) SDRAM, are widely used in various computer systems. When these computer systems execute programs, the relevant programs and data executed by the CPU (central processing unit, central processing unit) need to be put into the DRAM first. When executing the program, the CPU fetches instructions from the DRAM and executes the instructions according to the content of the current program pointer register. , and then fetch the...
