The ColdFire V2 - V4 targets collect the profiling information by using the profiling system. These targets do not have the hardware capability to collect trace. The ColdFire V1 target perform tracing and profiling using the target hardware. The profiling system consists of three main components:

• The statically-linked code library of compiled code containing the profiler
• An Application Programming Interface (API) to control the profiler
• The Simple Profiler Viewer to view and analyze the profile results
