基于FPGA的串口读/写EEPROM控制器设计

Design of Serial Read/Write EEPROM Controller Based on FPGA

为解决存储器难控制问题,笔者将Cyclone Ⅳ E系列的FPGA作为核心控制器件,提出改进型I^2C总线协议和串口接收模块设计方式,并结合EDA技术"自顶向下"的方式,设计了一种基于FPGA的串口读/写EEPROM控制器。经仿真测试,该控制器具有方便、可靠性强等优点。

In order to solve the problem of memory hard to control,the author takes the FPGA of cyclone Ⅳ e series as the core control device,proposes the improved I^2C bus protocol and the design method of serial port receiving module.Combined with the "top-down" mode of EDA technology,a serial port read / write EEPROM controller based on FPGA is designed.The simulation results show that the controller is convenient and reliable.
