Static profiling of the worst-case in real-time programs
Florian Brandner, Stefan Hepp, Alexander H. Jordan · 2012
With the increasing performance demand in real-time systems it becomes more and more relevant to provide feedback to engineers and programmers, but also software development tools, on the performance-relevant code parts of a real-time program. So far, the information provided to programmers through tools was limited to an estimation of the worst-case execution time (WCET) and its associated worst-case execution path (WCEP). However, these metrics only provide partial information. Only those code parts that are on one of the WCEPs are indicated to the programmer. No information is provided for all other code parts. To give an accurate view covering the entire code base, tools in the spirit of standard program profiling tools are required.
