The HIRFL-CSR EVMEbus controller is developed in IMP. The controller is based on AT91RM9200 (ARM9) microprocessor

which is in 0.8 mm BGA package. The controller runs LINUX OS

and can connect with standard VGA display

keyboard

and mouse. There are 10M/100M Ethernet

USB

RS-232

RS-485 and CANBUS interfaces on the board. It supports storage devices SD Card and CF Card. The backboard interface logic is pro- grammed in VHDL and is programmed into an in-system configurable FPGA device. The bus can drive high current up to 64 mA. It is not only compliant to VME specification

but also has flexibility of the programmable signal defini- tion. Being a key module in HIRFL-CSR control system

the controller can be used as a local controller and also a remote gateway controller.
