一种基于 FPGA 的 I2C 总线控制器的设计

摘要

An interface controI er of I2C bus is designed in this paper.With the extra protocoI Iayer process function,the controI er can aIso reaIize the controI of AT24 series EEPROM that based on the I2C protocoI.The design is impIemented on the FP-GA pIatform using the VHDL Ianguage.The functionaI simuIation is taken and the design is verified on the experiment board.%设计了一种 I2C 总线接口控制器，该控制器具备协议层处理功能，可以实现对基于 I2C 总线协议的 AT24系列存储器的控制。在 FPGA 平台下利用 VHDL 硬件编程技术实现了该设计，进行了功能仿真，并在实验板上完成了验证。
