文章介绍了一个面向SOC设计的可变规模的LeD驱动IP核,该IP包括四个独立的LeD驱动单元(DU)。不仅可以通过配置该IP使四个独立的Du分别驱动不同规模的LCD,而且能够实现四个Du级联来面对更复杂的应用场合。此外,设计了一个与wishbone总线相兼容的接口模块wrapper,并将该IP结合wrapper模块嵌入到0R1200平台来进行系统级的仿真验证。仿真结果表明该IP达到了设计要求,且通过修改wrapper模块可使该IP核适用于不同的SOC设计平台。

This paper describes a scalable LCD driver IP for SOC design. This IP includes 4 LCD driver units ( DU ). Not only can we make the four DUs to drive different scale LCD respectively, but also we may link them to deal with more extensive application. Moreover, a wrapper that is compatible with wishbone bus is designed. Verification based on OR1200 platform into which LCD driver IP and wrapper are embedded was given. The simulation result shows that this IP reach the design requirement and we can modify the wrapper module to make this IP used in different SOC design platform.
