The Design of an I²C Controller Supporting Multi-Mode Transmission

This paper presents an I²C controller supporting multi-mode transfer.It not only implemented the standard I²C bus specification,but also had some extension.It can support both master and slave,can select 5 transmission directions, and has several ways of address calling,etc.This paper emphasizes the design of the finite state machine and the controller of sending and receiving.All of functions and timing parameters were verified by RTL simulation and FPGA simulation.
