Abstract: Provided is a method for implementing compiled embedded Python. The method comprises: traversing an abstract syntax tree of Python source code to obtain semantic information about a program and generating corresponding C++ code according to said semantic information (S1); performing type annotation of the Python source code and thus generating C++ variable definitions and function definitions (S2); using a translator to translate into C++ source files the Python source code processed in the steps described above (S3); storing said C++ source files together with embedded chip-related files to form a file package, and compiling and linking said file package and generating an ASCII text file (S4). The method implements a source code translator on the basis of type annotations and static analysis, and integrates the translator into an embedded platform, enabling the editing, compiling, linking, and programming of Python source files.

Abstract: The present invention provides a thread signal operating method and system of an embedded real-time operating system, which relates to the technical field of communications. The system includes a main control module and a PC. A core of the main control module is an MCU chip and includes a serial port and a USB port. The serial port is used as a default communication device to communicate with the external. The USB port is connected to a USB port of the PC. The main control module further includes an actual thread signal waiting module, an actual thread signal setting module, a system service call interrupt module, and a suspendable system call interrupt module. Multi-threaded signal processing according to task allocation rules can reduce overhead caused by interactions, improve processing efficiency, reduce power consumption, and reduce hardware module superposition.
