Abstract

The EVME bus controller which is a key component of the HIRFLCSR control system was improved . Besides reconfiguring the embedded Linux， a utility program was developed for data exchange between the controller and the database. The bus controller is based on ARM920T(ARM9) micro processor which is BGA packaged. The bus controller has the universal interface of VGA display， keyboard， and mouse. The backboard interface logic is programmed in an insystem configurable FPGA device. The bus can drive high current up to 64 mA， with the flexibility of the programmable signal definitions. All the improved performance helped the EVME bus controller play a crucial role in HIRFLCSR control system.
