Method for processing data of embedded system

Abstract

A data processing method of embedded system includes: a controller, a volatile memory and a non-volatile memory; the layout data of the system is added with label and grouped, many labels are set into one group and marked a label, it is then memorized in the non-volatile memory; the set data of system is received; the group label of all the layout data is searched; judging whether the set data of system is uniform to the layout data searched; if the set data of system is uniform to the layout data searched, the layout data searched will be loaded to the volatile memory; the layout data in the volatile memory is read out by the controller to accomplish the self-initialization to start work. Said data processing method of embedded system takes use of searching group label to lead in the layout data, the time of system configuration and the occupancy of volatile memory when system is running normally can be effectively reduced.

Description

【Technical field】 [0001] The invention relates to a method for processing data by an embedded system, in particular to a method for rapidly processing data by an embedded system. 【Background technique】 [0002] With the rapid development of network communication technology, especially the development of wireless network, various embedded systems have gradually become the main tool for people to obtain data. Today's mobile phones, modems, gateways, etc. are all embedded systems. [0003] An embedded system generally consists of the following modules: a controller, a non-volatile random access memory (NVRAM) for storing firmware (Firmware), and a volatile memory for storing program data. memory (volatile random access memory, VRAM), a lightweight embedded operating system, and the like. [0004] Since all the configuration data in the embedded system are stored in the non-volatile memory, when the embedded system is working, the system configuration data needs to be loaded, ...

AI Technical Summary

Problems solved by technology

Under normal circumstances, when the system is working normally, the microcontroller does not need all the configuration data, it only needs to provide the configuration data consistent with the system settings, so the method of directly storing all the configuration data into the volatile memory, in When the embedded system is working, a lot of volatile memory space will be wasted, and all configuration data will be imported from the non-volatile memory to the volatile memory, and the controller will search for the required configuration data one by one in the volatile memory. This method seriously restricts the working speed of the whole system

[0005] In order to solve the above problems, a tag storage method has emerged, that is, adding a tag before each value (value), so that when the system imports configuration data, the required configuration data can be sequentially identified according to the tag. But this method still has a shortcoming. When the system is powered on for the first time, it is still necessary to import all the configuration data together with its tags into the volatile memory so that the microcontroller can search for the required ones in sequence. Configuration Data

Therefore, this method still occupies a large amount of space in the volatile memory to a large extent, and it still takes a lot of time to import all configuration data from the non-volatile memory to the volatile memory
