A high performance profiler for embedded IDE

Performance problem has been the focus of embedded software development. An instrumentation method is promoted in order to get the execution time and the number of times a function was called. And how to implement a profiler, profiling the programs running on ARM processors with Linux, is discussed through that method. This paper also gives the comparison between our profiler and others' methods in use. The result shows that our profiler has more advantages than some popular profilers in Linux in profiling recursive or library functions.
