Then calculations are done within same quanta/period it does not matter if they are executed in a sequence after each other or in parallel by several CPUs. > (My second guess is that I have misunderstood the question) > > Basically, by the time any HAL component reads its inputs all the > upstream components have updated their outputs. It depends on hardware but to simultaneously sample inputs and actuate outputs is a good method. Then computations could happen anywhere within period and it also agree with theories for real time scheduling. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
