aiT for i386DX statically computes tight upper bounds for the worst-case
execution time of tasks in real-time systems. It directly analyzes
binary executables and takes the intrinsic cache and pipeline behavior
into account.
Key benefits
- The static analysis guarantees that the computed WCET bounds are
valid for all possible inputs, all possible cache and pipeline states,
and each task execution under any circumstances. With that,
extensive timing testing is a thing of the past.
- aiT directly analyzes binary executables, exactly as they are
executed in the final system. This requires no modification
of your system’s operational behavior or performance,
and no modification of your toolchain.
- aiT-computed bounds are extremely tight
and thus reflect the actual performance of your system.
Deadline adherence is ensured without wasting hardware resources.
- aiT lets you easily save and compare the analysis results
before and after making changes to your system, such that their
effect on the worst-case timing can be understood immediately and completely.
- Using aiT is essential in meeting current safety standards
such as ISO 26262 and DO-178B/C, where static
WCET analysis is part of the architectural safety requirements.
