A Profiling Tool for Heterogeneous Multi-core Systems

Profiling is a process of collecting relevant data about the execution of an application. This is done in order to reveal code bottlenecks, measure the performance, and give detailed information about source code function contents and call graphs of the examined application. In this paper we present one such profiling tool designed for multi-core systems, which collects information about the multi-core activity and machine code statistics. The tool is implemented as part of the framework for development, deployment, debugging and control of DSP applications, and includes a profiling view which improves user experience and understanding of the profiling reports. Profiling reports can be used for improving the quality of the written code as well as to ease the process of debugging.
