本文论述了最优扫描结构的分形理论模型到通用逻辑算法的推导、分形扫描方法在平板显示灰度控制中的关键技术研究及IP核构造.根据建立的平板显示器(FPD,Flat Panel Display)分形扫描核心模块架构,导出相应的n位分形扫描的递推结构及硬件逻辑实现模型,然后研究每个扫描时间对应的子空间码和位码序列的生成及逻辑实现,其中采用格雷编码定位器优化策略生成子空间码序列,可简化硬件逻辑、提高系统的抗干扰能力.在此基础上设计了适合各种灰度等级的、具有自主知识产权的分形扫描软核,仿真结果证明所设计的IP核达到预期目标,可嵌入于FPD扫描控制器中,有效提高了灰度扫描的利用率和和FPD画面质量,更重要的是使具有自主知识产权的平板显示器分形扫描方法得以工程实现.

This paper presents the general logic algorithm deduction based on the fractal theory model of optimal scanning architecture,research on the key technique of fractal scanning method in FPD （Flat Panel Display） gray scale controlling and the IP core designing. The studying content included the fractal scanning core scheme and n bits recurrence structure, creation and logic implemention of sub-space code sequences which can simplify hardware and raise anti-interference ability by applying the gray code locator. On the facts mentioned above, we have completed the fractal scanning lP（Intellective Property） core which can adapt to all kinds of gray scales,and the simulation results indicated that the designed IP core accords with the prearrange objective.The novel fractal scanning IP cote embedded in FPD scanning controller can efficiently increase the scanning availability and the FPD imaging quality, and the more important fact is that the creafionary control method gets the engineering implementation.
