Design on Interrupt of VXIbus

Combing with the developing of internal controller of VXIbus, this paper discusses the VXIbus interrupt process in detail.The interrupt management of the VXI interface circuit is given.Considering the difference between VXIbus and ISAbus in handling the interrupt, this paper also presents a circuit designed to achieve the transition between the two different buses, which can be used to design VIXbus controller module.
