Embedded type device CPU and its peripheral equipment state real-time monitoring method and system

Abstract

The invention relates to an embedded type device CPU and its peripheral equipment state real-time monitoring method and system. A peripheral equipment state acquisition unit is designed on an embedded type device software platform for reading peripheral memorizers of the embedded type device CPU in real time, various states of various kinds of peripheral equipment are obtained, state information is sent to a PC client, and the PC client displays the state information for debugging personnel to analyze the state information. In the embedded type development process, various peripheral registers are timely read so as to check and analyze the peripheral equipment states, when peripheral equipment is abnormal, only by analyzing data recorded by the system, problems can be timely found, test codes do not need to be wrote, burning for abnormity recurring is also not needed, positioning and recurring of the problems are convenient, after it is observed that the peripheral equipment is abnormal, processing is conveniently conducted in time, and the efficiency of testing is thus improved.

Description

technical field [0001] The invention belongs to the field of embedded technology, and in particular relates to a real-time monitoring method and system for the state of an embedded device CPU and its peripherals. Background technique [0002] In the embedded development process, it is often encountered that abnormalities occur in CPU peripheral debugging. After an exception occurs, many times, programmers will "guess" where the problem occurs based on their own experience. Of course, it will also be analyzed by reading various registers of peripherals, and finally find the exception. However, this process is often cumbersome, and it takes time to locate and reproduce some problems, because some problems can only be reproduced in a very special test environment. Moreover, sometimes although a large number of peripheral data are recorded, there is a lack of automatic analysis tools, which consumes a lot of time in analyzing abnormal points. During the R&D process, various o...
