Model Checking Interrupt-Dependent Software
Embedded control programs are hard to analyse because their behaviour depends on how they interact with hardware devices. In particular, embedded code typically uses interrupts to respond to external events in a timely manner. Such asynchronous control constructs make static analysis difficult due to the potentially large number of alternative control-flow paths they allow. We show how model checking can be used to effectively analyse the behaviour of interrupt-dependent programs. This is done by developing an abstraction of the code that captures its essential timing and functional properties, including those related to external interrupts. The model is made efficient by grouping program instructions into basic blocks whose behaviour is atomic with respect to interrupts.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
