基于FPGA的I^2C总线应用研究

Application Research of I^2C Bus Based on FPGA

I2C总线作为高性能的串行传输总线,已在微电子领域得到了广泛的应用。本课题中,在EP2C5Q208C8N平台上采用硬件描述语言VHDL,通过Moore型有限状态机编程设计了模数转换器件PCF8591T的I2C总线控制器。实验结果表明:所设计的I2C总线控制器遵循I2C总线接口协议,数据传输稳定可靠。

As the serial bus of high performance, I2 C Bus has been widely used in the field of microelec-tronics. Using hardware description language VHDL and Moore finite state machine, the I2 C bus control-ler of analogy-to-digital converter PCF8591 T was designed through programming on EP2C5Q208C8 Nplatform. The experimental results show that the I2 C bus controller is stable and reliable by I2 C bus in-terface protocol.
