摘要
In this paper,a general method of data transmission system design on PXI platform is proposed.It can be used in readout system design for physical experiments.It aims at providing reusable and general interfaces for customized design of PXI while maintaining the transmission performance.It has three main features:(1)universal logic hardware interface,(2)ethernet based socket software interface,and(3)specific and simple data transmission protocol.Data transmission on PXI bus can be realized with the said two universal interfaces coordinated by this specific protocol.Test shows that this method is feasible and stable.This method can be easily reused in readout system designs for different experiments.
In this paper, a general method of data transmission system design on PXI platform is proposed. It can be used in readout system design for physical experiments. It aims at providing reusable and general interfaces for customized design of PXI while maintaining the transmission performance. It has three main features： （1）universal logic hardware interface, （2）ethemet based socket software interface, and （3）specific and simple data transmission protocol. Data transmission on PXI bus can be realized with the said two universal interfaces coordinated by this specific protocol. Test shows that this method is feasible and stable. This method can he easily reused in readout system designs for different experiments.
