Abstract

A real-time beam profile diagnostic platform based on embedded ARM and FPGA has been developed for beam cross-section measurement of the SDUV-FEL(Shanghai Deep Ultra-violate Free Electron Laser).In this paper

we report the interface design of the stepper motor control subsystem.The interface is implemented through the ARM external bus

and the driver for FPGA device is developed under Linux operating system.The interface board is designed and fabricated from chips level in order to evaluate the hardware performances of different functional modules.Test results of the motor control subsystem show that the motor location resolution is about 2 μm for the interface board.The architecture is scalable and suitable for further application in FEL facility.
