Dummy-based instruction execution method, computing equipment and storage medium

Abstract

The invention discloses a dummy-based instruction execution method, computing equipment and a storage medium. The method comprises the steps of: submitting a first storage instruction of storage data applied in an internal memory to a processor; generating a second storage instruction according to a data storage abnormality message generated by the processor; writing in the dummy according to the storage address of the data stored by the second storage instruction; executing the second storage instruction through the processor to store data in the internal memory, and replacing the stored dummy; when a first reading instruction for reading data in the internal memory is received after the dummy is written, executing the first reading instruction through the processor, and judging whether the dummy is read or not; if the dummy is read, prompting that the read data is invalid, and executing the first reading instruction again through the processor; and if the dummy is not read, reading the data through the first reading instruction. According to the method, the atomicity of data access and storage is not lost, and the problem that some special application programs run abnormally is avoided.

Description

technical field [0001] The invention relates to the field of computer instruction execution, in particular to a dummy element-based instruction execution method, computing equipment and a storage medium. Background technique [0002] With the continuous development of computer technology, more and more applications have been developed. Correspondingly, the application data is also increasing, and the data structure is becoming more and more complex. Therefore, the access performance of the system to complex data structures in the memory is becoming more and more important, which directly affects the running speed of key applications. When data is stored, there are often special storage situations. When the application accesses these stored data, the processor does not support special access instructions for the data, and errors will be reported. The processor cannot directly handle this type of access. Store instructions to manipulate data. [0003] For this reason, in th...

[0004] But this method converts one memory access into multiple memory accesses, thus essentially changing the memory access model of the application

For some special application scenarios, the atomicity of one memory access is destroyed by multiple memory accesses. If the application relies on the atomicity of memory access, in this case, it will be caused by the destruction of atomicity. Errors or errors in the data may cause the application to run abnormally in severe cases
