On-line real-time debugging method for panoramic data on basis of denomination variation

Abstract

The invention discloses an on-line real-time debug method for panoramic data on the basis of denomination variation, belonging to the technical field of dynamic memory debugging for embedded software. By a registration system, a dynamic object (the embodiment of a structure) registers the name and the memory address of the object to a debugging agent program via a communication link during initialization; the debugging agent program is combined with a locally stored member variable offset table to generate the address information of all members (dynamic variables) of the object; and the address information is supplied for a host debugging system for on-line debugging. With the method, the device can be debugged on line in real time under the condition of uninterruption and no restarting and is used for tracking the operation state of the system. Through the application of the debugging method, the development efficiency of protective application developers and the engineering maintenance efficiency of the engineering maintenance personnel are improved.

Description

technical field [0001] The invention relates to an online real-time debugging method of embedded software. Background technique [0002] With the development of embedded systems, embedded systems are now used in almost all electronic and electrical equipment, high-end embedded processors have been widely used, system-on-chip, deeply embedded, distributed multi-processor The development of speed has brought great challenges to traditional debugging methods. Debugging is an essential part of the embedded system development process, which accounts for 20% to 30% of the entire development time. Its importance is self-evident. [0003] The traditional debugging method is to connect with the embedded system through the emulator, run the integrated development and debugging tool on the host, and the debugging tool has editing, compiling, linking and debugging environment, because the symbol table information of the embedded system is saved in the debugging environment of the host...

Problems solved by technology

This debugging method has obvious disadvantages: it takes up more system resources, and some systems must rely on the JTAG port of the chip. The emulator and debugging tools are expensive, and it is not possible to perform plug-and-play debugging on the running system, and it needs to be restarted before debugging. System, re-downloading programs and other cumbersome steps

The dynamically allocated variables are allocated during the initialization of the program, and the address of these variables is unknown before running. Since the CPU runs binary instructions, the corresponding relationship between the memory address and the variable is not known during the running process, so These dynamically allocated memory lack effective debugging methods
