If one wants to create structured , modular code , timing IS
deterministic . But i code it into the kernel , so he calc's it ....
he knows exactly when to do every task ...
Even in the VN mem module , ARM7 , it is deterministic ,
if you disipline yourself to structured code .
But you must not do this urself , let the kernel calc and
control all the idle time...
Computers arent like humans , they wont "create" idle , like
a Trade Unionist !!
BTW comming soon to a theater near you , a free OpSys
for ARM . Its so structured , takes minutes to figure
everything in the kernel , then use those patterns
to disassemble any code !!

Hi,
in real-time systems the worst case execution time (WCET) is an important
issue. In the literature I found the statement that its calculation is
undecidable in general. Why? I appreciate a detailed explanation.
