摘　　要：本文论述用于兰州重离子加速器冷却存储环(HIRFL-CSR)控制系统的前端总线系统控制器FBC-01的硬件设计。该控制器是基于0.8mmBGA封装的AT91RM9200(ARM9)处理器,运行嵌入式LINUX操作系统。控制器可以连接标准的VGA显示器、键盘、鼠标,具有通用的10M/100M以太网接口、USB接口、RS-232接口、485接口、CANBUS接口。可以带SD卡、CF卡存储器。该控制器采用现场可编程的FPGA器件设计背板接口,并采用具有64mA高驱动能力的总线驱动器,不仅符合VME规范的电气要求,而且具有灵活的接口信号定义可编程能力,是HIRFL-CSR控制系统的关键部件。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 programmed 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 definition. Being a key module in HIRFL-CSR control system, the controller can be used as a local controller and also a remote gateway controller.
