基于Nios II数据采集模块控制器的设计

为实现基于Nios Ⅱ图像识别系统的软硬件协同图像识别,基于可编程片上系统(SOPC)最新技术,结合图像识别系统的设计原理,给出了该系统中Avalon总线外设数据采集控制器的设计方法。该方法解决了系统中硬件和软件对同步动态随机存储器(SDRAM)访问冲突的问题,从而达到了软硬件协同处理图像的目的,对图像处理的速度和灵活性都有改进。实际操作表明该方法亦适用于其他存在同类问题的系统中。

Nios II-based data acquisition module controller design

In order to achieve the synergetic image recognition of hardware and software, an Avalon bus peripheral data acquisition controller based on the latest technologies of System On a Programmable Chip(SOPC) is designed combined with the design principles of image recognition system. The proposed method can solve the conflicting issues when the hardware and software systems access Synchronous Dynamic Random Access Memory(SDRAM), therefore it can realize the synergetic image recognition of hardware and software systems as well as improve the speed and flexibility of the image processing. The actual operation of the method indicates that it is also applicable to other systems with similar problems.
