【摘要】：CIS图像传感器具有体积小、重量轻、抗震动、装配简单等特点，在地图、广告和工程图纸等大幅面扫描领域常选用CIS作为其图像传感器。SOPC（Systemon a Programmable Chip可编程片上系统）是基于FPGA（Field Programmable GateArray现场可编程门阵列）解决方案的SOC（System on Chip片上系统）技术。论文的主要工作为利用SOPC技术设计与实现CIS扫描控制器。本文在分析研究已有扫描控制器工作原理的基础上，结合可编程逻辑技术，，提出了基于SOPC的CIS扫描控制器实现方案；通过对CIS图像传感器CIPS305BF600的分析，设计了基于WM8213模拟前端处理器（Analog Front-endProcessor，简称AFE）的CIS扫描驱动电路；在对CIS图像扫描控制过程进行研究的基础上，通过可编程逻辑设计，实现了AFE模拟前端的SPI配置接口、像点数据采集、动态像点校正、图像数据存储及USB图像数据上传等逻辑功能模块；然后，通过逻辑封装技术对设计实现的各逻辑功能块进行自定义组件的封装，并集成了基于SOPC的CIS扫描控制器；最后，通过对Nios II编程，实现了对整个扫描过程的控制。经时序仿真和系统功能测试，研究结果达到了设计要求。基于SOPC的CIS扫描控制器的设计实现，不仅降低了控制电路的复杂性和成本，而且提高了扫描控制系统的性能。实现结果对高速、宽幅CIS扫描设备的设计及应用，具有一定的借鉴价值。
[Abstract]:CIS image sensor has the advantages of small volume, light weight, anti vibration, simple assembly and other characteristics, on the map, advertising and engineering drawings and other large format scanning field often uses CIS as its image sensor.SOPC (Systemon a Programmable Chip programmable system on chip (Field) is based on the FPGA Programmable GateArray field programmable gate array) solutions SOC (System on Chip system on chip) technology. The main work of this paper is using SOPC technology and implementation of CIS scanning controller design.
Based on the analysis of the working principle of the scanning controller, with programmable logic technology, proposed CIS scan controller based on SOPC; through the analysis of CIS CIPS305BF600 image sensor, the design of WM8213 processor based on the analog front end (Analog Front-endProcessor, referred to as AFE) CIS scan driver circuit has been studied in this paper; CIS image scanning control process, the programmable logic design, realizes SPI configuration interface AFE analog front-end, such as data acquisition, dynamic image correction, image data and USB image data upload logical function module; then, through logical packaging custom component package of the logic function design the block, and the integration of CIS scanning controller based on SOPC; finally, through the programming of Nios II, the realization of the whole scanning process control After the time series simulation and the system function test, the research results have reached the design requirements.
The design and implementation of CIS scanning controller based on SOPC not only reduces the complexity and cost of control circuit, but also improves the performance of scanning control system. The implementation result has certain reference value for the design and application of high-speed and wide CIS scanning equipment.
