Abstract

In accordance with one aspect of the invention, a system for generating compact function trace data for leaf functions includes a central processing unit (CPU), configured to output program flow information needed for generating a program flow trace, and a trace unit, coupled to the CPU. The trace unit is configured to receive the program flow information from the CPU for generating compact function trace data. The trace unit further comprises a first output mode and a second output mode and is further configured to select either the first output mode or the second output mode for generating compact function trace data.
