基于MicroBlaze软核处理器的图像采集系统设计

Designing of Image Gathering System Based on Soft-core MicroBlaze Processor

针对传统图像采集系统功能单一及调试困难等缺点,在图像采集与处理系统中引入基于MicroBlaze软核处理器的SOPC;通过平台FPGA设计技术,在一片可重构SOPC中集成了一套用于图像数据采集与阶段调试的系统,内部OPB总线上采用自定义的IP核实现图像数据的采集与缓存控制,并通过USB口将图像处理数据向主机PC进行实时的转送;通过实验验证以及系统最终实现表明,该设计能快速高效地完成图像数据的采集与系统实时调试,具有体积小、可重构、稳定性好等特点,并已应用于某一科研相机的图像采集与处理系统中。

A SOPC based on soft-core MicroBlaze processor was applied to an image gathering and processing system.Grounded on the FPGA platform SOPC design methodology,an image gathering and phase debugging system are integrated into a single reconfigurable SOPC.The self-define IP cores based on OPB bus in the SOPC are designed to gather and buffer the image data,and send signal to host PC through USB port.Both experimental verification an final implement indicate this design can fulfill the tasks of image gathering and debugging flexibly and quickly,and also holding the feature of smallness,reconfigurable and high reliability.This design has already adopted in image gathering and processing system for a scientific camera.
