Evaluation of an Additive WCET Model for Software Components
Publication Type:
Conference/Workshop Paper
Venue:
WTR 2008 10th Brazilian Workshop on Real-time and Embedded Systems
Abstract
The use of component technology in embedded systems
brings new challenges to this domain. One important
issue is how to derive properties of the system
when we know the properties of the system's components.
When the system is real-time, it is useful to find
out how component composition will affect the execution
time of tasks made out of components.
In this work, we use a statistical design to
examine and rank different hardware
features with respect to
their impact on the execution time at component composition.
Our results indicate, for example, that main memory latency and
the block size of the L2 cache have the greatest effect, while
memory bandwidth has the least effect.
