多集成电路制造商均提供了多种功能强大的I2C总线应用芯片。I2C总线大量应用在视频、音像系统中,在I2C总线技术上还有许多工作可做,如位方式的数据通信；由ACCESS.BUS构成的桌面多机系统及网络等。本课题就是居于这方面的考虑，设计一个基于FPGA的I2C总线通信系统。-Many IC manufacturers offer a variety of powerful application chip I2C bus. I2C bus is widely used in the video, audio and video systems, I2C bus technology in a lot of work to do, such as bits of data communication means　posed by the ACCESS.BUS desktop multi-machine systems and networks. This topic is considered living in this area, to design a FPGA-based I2C bus communication system.
