The worst-case execution time (WCET) is an upper bound on the execution of tasks. Computing such a bound is undecidable in the general case. Computing tight upper bounds on the execution time may still be difficult.
Composability may suffer from this.
Due to its focus, it is a rather compact OS.
. . . comfortable main stream operating systems.
. . . become quickly available in the embedded world as well.
. . . in order to guarantee meeting timing constraints.
A sequence of read and write operations is called a transaction.
Hence, changes caused by transactions are normally not considered to be final.
A platform is a family of architectures satisfying a set of constraints imposed to allow the reuse of hardware and software components.
