摘　　要：为满足嵌入式系统中专用芯片功能不能达到系统要求的现状,设计出一种功能可扩展的I2C slave控制器,这种控制器与传统的专用I2C芯片不同。专用的I2C芯片的功能具有固定性,只能实现一种或两种功能,而这种控制器是在FPGA上实现的。由于FPGA本身就具有可编程性,因此这种控制器也可以实现不同的功能,来满足在嵌入式系统中对某种功能的需求,具有可定制性。结果表明,该控制器可以正确的从I2C总线上接收数据,并根据所接收数据来控制与控制器相连的外设,比专用I2C的芯片使用起来更灵活。Describe the FPGA, I^2C, Verilog basic concepts, together these three technologies design the I^2C slave controller on FPGA. The controller can receive data from the I^2C bus, it first determines whether the received address data match to their own address, If it matched and then analyze the received data, according to data received from the bus to control peripherals. Finally, in the preparation of testbaneh in modelsim simulation in I^2C bus to send data to the top of the I^2C slave controller module sends excitation signals to verify the correctness of the module. The results show that the controller module design is correct and has been designed to achieve the purpose ,which you can control the peripheral modules.
