'''Introduction:''' [http://sourceware.org/binutils/docs/gprof/ gprof] is a tool for profiling an application. It is a statistical profiling tool, which means that it samples an application to determine where the application spends its time. Supporting profiling of RTEMS means supplying the [http://sourceware.org/binutils/docs/gprof/Implementation.html#Implementation necessary functions] for profiling, in particular the mcount and profil routines, and adding some statistic tracking to RTEMS. [http://www.rtems.org/ml/rtems-users/2010/may/msg00099.html This e-mail] describes how this was accomplished on the LEON target, and gives some ideas for a design to support profiling RTEMS.

'''Goal:''' To design and develop support for gprof profiling in RTEMS.

'''Requirements:''' List the requirements and level of expertise you estimate are required by the developer tackling this project will have to have: Required level of programming language(s), specific areas of RTEMS or tools, level of familiarity with RTEMS, cross-development, GNU/Linux, etx., development/documentation/testing tools, mathematical/algorithmic background, other desirable skills.
