GPIB接口控者功能的FPGA实现

Realization of the Controller Function Based on FPGA for GPIB Interface

针对专用GPIB控制芯片价格昂贵、购买困难等问题,采用低成本的FPGA器件替代专用GPIB控制芯片来实现GIPB接口控功能,并给出了具体的实现方案。该方案基于FPGA器件,采用VerilogHDL语言编程,并在QuartusⅡ下进行编译、综合和仿真,最后下载到FPGA器件上,成功实现了GPIB接口控功能。仿真和实验均表明,该方案大大节省了成本,移植性好,具有很强的灵活性。

Aiming at the difficulties in application of GPIB control chip,e.g.,expensive and hard to purchase,it is put forward that using low cost FPGA device to replace dedicated GPIB control chip for implementing GPIB interface control function.The specific implementing strategy is given.Based on FPGA device,by adopting Verilog HDL programming language,compiling,integrating and simulating under Quartus II,then downloading into FPGA device to fulfill the control function of GPIB interface.The simulation and experiment show that this strategy greatly decreases the cost,and offers good transplantation performance and higher flexibility.
