Embodiment Construction

[0041] see figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the log storage method of the embedded system of the present invention.

[0042] The log storage method of the described embedded system of the present embodiment comprises the following steps:

[0043] Step 101, acquiring log data of an embedded system.

[0044] Step 102, write the log data into random access memory.

[0045] Step 103, copy the log data written in the random access memory to the external memory.

[0046] In the log storage method of the embedded system described in this embodiment, the log data is first stored in the random access memory, and then the log data is copied from the random access memory to the external memory. On the embedded software system, it can not only guarantee the normal operation of all tasks, but also save the log data quickly with a low memory utilization rate, and the log data copied from the random access memory to the external memory will not ...

Abstract

The invention discloses a log storage method and system of an embedded system, and a log reading method and system. The log storage method includes: acquiring log data of the embedded system; writing the log data into a random access memory; The log data written in the random access memory is copied to the external memory. In the log storage method and system of the embedded system and the log reading method and system of the present invention, the log data is first stored in the random access memory, and then the log data is copied from the random access memory to the external memory. On the embedded software system, it can not only guarantee the normal operation of all tasks, but also save the log data quickly with a low memory utilization rate, and the log data copied from the random access memory to the external memory will not lost. The log data can be quickly read from the random access memory, and the lost log data of the random access memory can be read from the external memory in time.

Description

technical field [0001] The invention relates to the field of embedded systems, in particular to a log storage method and system of an embedded system, and a log reading method and system. Background technique [0002] In terms of log storage in embedded systems, it is necessary to save files quickly and without order, and read out log data according to user needs. With the continuous advancement of technology, the demand for saving operation files in designated locations is getting higher and higher, and to read out different required data according to requirements, it is necessary to ensure time efficiency and simplicity of data. In the embedded system, mainly by directly storing the log file in the RAM (random access memory, random access memory) connected with the CPU. [0003] However, storing the log files directly in RAM is easy to lose the log files after the system is powered off. Contents of the invention [0004] Based on this, it is necessary to provide a log ...
