NiosII的I2C控制IP及其在成像系统中的应用

详细介绍一种I2C控制IP的工作原理及其可编程寄存器,给出该IP在CMOS数字成像中的应用实例。该实例基于可编程片上系统（SOPC）技术设计,在NiosⅡIDE中通过编写程序来实现系统功能,并通过QuartusⅡ软件自带的SignalTapⅡ进行验证。结果表明,在CMOS成像领域选用该IP核,系统能充分利用SOPC技术的优势,具有扩展性好、控制灵活、开发周期短等特点。

NiosII-based I2C Controller IP and Its Application in Imaging System

The working principle of an I~2C controller IP core is introduced,and the programmable registers of the IP core are described. The paper gives an application instance of CMOS digital imaging based on system-on-a-programmable-chip(SOPC) technology,and realizes the function by programming C code in NiosII IDE software.The system is tested by SiganalTapII of QuartusII.The system taking advantage of SOPC technology by using the I~2C IP,experimental results show that it has the characteristics of good expansibil...
