Linux Embedded system running time is unstable-Linux general technology-Linux technology and application information, the following is a detailed description. The running time of Linux embedded systems is unstable.
An embedded linux system created using busybox + 2.6.32.13 has a single processing process and a single task.
The same processing process processes the same data. In most cases, the processing time is a relatively stable value, generally around 50 ms. However, sometimes 160 ms, 120 ms, or even ms occurs. The frequency of appearance is also large. The cpu is sometimes occupied by other system processes. There is no access to peripherals in the application, and there is no disk read/write. The data required by the program is read into the memory during initialization, and the memory is also large, 1G, 2G. The application requires about MB of memory. Which of the following experts can help me to make the running time stable at around 50 ms? Thank you.
