Research and optimization on dynamic performance analysis of code in embedded environment

The efficiency and space complexity of program are very important for embedded software. Therefore, it is great reference value to analyze the execution time and calling times of code for optimizing embedded code. Code instrumentation is the key technology of monitoring program performance. Static instrumentation on the executable file is a method and strategy that can achieve the dynamic analysis program performance. The tool can analyze the execution time and calling times of user function and the embedded library function. Through analysis and comparison, this method is faster and more accurately than the existing statistical tools.
