The Design and Simulation of IIC Communication SOPC Core Based on Avalon Bus

In this paper, we designed IIC into adjustable IP (Intelligent Property) core to shorten the develop cycle of IIC interface and improve the reconstruct ability of the system. In SOPC Builder, the hardware design code of IIC was integrated and defined as a port signal type, forming a called IP core. As a result, the development efficiency of the system is enhanced, the reliability of the system become high and the design of the system is less complicated.
