Problems solved by technology

[0002] As the current embedded products are becoming more and more complicated, the requirements for software are also getting higher and higher. In the process of product development, there will be statistics on the use of memory chips with specific addresses. From the link files generated by the compiler, you can intuitively obtain specific The storage location of functions or variables, but the size of data in a specific address space cannot be obtained intuitively. In order to obtain the usage of resources in a specific address range, developers need to check the map file, find qualified data, and manually calculate the usage of resources.

Embodiment

[0035] Such as Image 6 shown by tag to get the compiler type, through The label obtains the storage path of the map file, through The label obtains the name of a specific address range, the start address is obtained through the label, and the end address is obtained through the label. After getting the information, match the information filtered out by the map file with these addresses, and then perform calculations, such as Figure 7 As shown, the final result is displayed in the form of a pie chart.

Abstract

The invention provides a python-based MCU (Microprogrammed Control Unit) resource automatic identification statistical method, which takes a python language as a development language, supports map files generated in IAR and GreenHill development environments, screens out useful information from the map files by utilizing a regular expression, matches the useful information with an address range in an XML (Extensible Markup Language) file defined by a user, and finally graphically displays the successfully matched information. The method has the beneficial effects that the chart data can be generated by one key, the use condition of each storage resource can be intuitively reflected, and support is provided for development work.

Description

technical field [0001] The invention relates to the technical field of MCU resource statistics, in particular to a method for automatically identifying and counting MCU resources based on python. Background technique [0002] As the current embedded products are becoming more and more complicated, the requirements for software are also getting higher and higher. In the process of product development, there will be statistics on the use of memory chips with specific addresses. From the link files generated by the compiler, you can intuitively obtain specific The storage location of functions or variables, but the size of data in a specific address space cannot be obtained intuitively. In order to obtain the usage of resources in a specific address range, developers need to check the map file, find qualified data, and manually calculate the usage of resources. . Contents of the invention [0003] In order to solve the above problems, the present invention discloses a python...
