Hunting Linux Time-Eaters with Hardware Based Tracing
TRACE32 Success Story
The ability to analyze the runtime behavior of a target system can be a very important, but often overlooked, part of the debug process. Often, in a real-time system a late answer is as bad as a wrong answer.
Various software tools exist, especially in the Linux world, to help measure the performance of an embedded system but sometimes they just end up compounding the problem.
This article shows how Advanced Driver Information Technology GmbH (ADIT) in Hildesheim used Lauterbach’s TRACE32, a non-intrusive hardware-based trace tool to overcome such a problem.
