Design of GPIB Interface for Programmable Inverter Power

介绍一种基于FPGA的程控变频电源GPIB接口设计方法,采用VHDL语言在XC3S400芯片上实现专用接口芯片NAT7210的功能。介绍了程控变频电源控制电路和FPGA实现的功能块框图,并给出了讲者接口功能的状态转换图及其实现方法,最后介绍了在PIC24单片机上实现GPIB驱动的设计方法。

In this paper,a design method of GPIB interface for a programmable inverter power based FPGA is introduced,which realized some functions of NAT7210 on XC3S400 FPGA chip using VHDL.The block diagram of this power control circuit and function developed by FPGA are discussed,moreover,the FSM diagram of Talker function and design method are presented in detail.Finally,the design of driver for GPIB on PIC24 MCU is introduced.
