Experimental Physics and
Industrial Control System

Reviewing EPICS Application Developer's Guide, I have noted some point in the figure contained in chapter 3, point 3.3 (IOC Software componentes) that let me a little bit confused. I am refering to the box "Driver or Device Interrupt Routines", that interconnects directly the line (VME) with the box "scanners". I have implemented some Epics Device support for RIO/FlexRIO devices using AsynDriver, and the way I have implemented is using interrupt calls, that in the upper layer of the asynDriver, are epics device standard docallback interrupts. This software layer I'll integrate in the box "Device Suport"... but then I don't know what the box "Driver or Device Interrupt Routines" refers to. Does It means that there is other ways in EPICS to implement pices of code that generate interrupts on the EPICS Core? Could someone explain or refering me to some document that explain this?

Thank you very much
