Hello all,
i'm working lately on an EPICS machine, where the number of PVs is 470 at the moment and they need to be updated regularly at 60Hz. The EPICS machine consists of the stuffs as:
. VME6100 (Mototorla VME CPU @1.25GHz) . RTEMS . EPICS (base-R3-14-12)
Currently all these updates for the 470 PVs is taken about 2-3.5 msec; which needs to be improved in a great manner for my 'real' project with about 23,980 PVs, to be updated regularly at 120Hz, after all.
Is here anyone who can give me some advice on this 'huge' improvement i need?
Best Regards Young-Wuk KIM |
