【摘要】 目前的人机交互技术,不管是通过键盘,鼠标,还是摇杆,手柄,都是人主动去适应设备,将多维的外部信息压缩成传统输入设备所能接受的信息流。在计算机领域,技术的发展趋势是向着人性化,自然化的方向迈进,眼标系统正是自然人机交互的一种方式。PC版的眼标系统需要耗费大量的系统资源,影响PC处理其他的工作,嵌入式的眼标系统如果采用多核并行架构,则可以实现眼标系统的实时控制。本文提出了一个嵌入式眼标系统的多核并行架构的具体实现。本文的主要工作体现在完成了在DSP平台上对部分眼标软件程序的测试,根据测试结果和相关资料,放弃了选用DSP核,而选取了三星高性能的s3c2440芯片作为眼标硬件系统的并行处理器,同时根据眼标系统的需求选择了一系列符合系统需求的元器件,包括恩智浦公司的ISP1564,Altera公司的EP2C15AF484C等等;最后在选择的这些元器件的基础上合理的设计硬件电路。本文为眼标硬件系统设计了6个模块,即一个主处理器模块、三个辅处理器模块,一个总线模块和JTAG下载调试模块,并完成了各个模块的硬件电路的设计。本文设计的眼标硬件系统,能够实现一秒钟处理10幅以上的图片,实现了眼标系统的实时控制。更多还原

【Abstract】 The current human-computer interaction technology, whether through the keyboard, mouse or through joystick handle, is all that requires people adapting the equipment, to compress the external multidimensional information into a flow of information that traditional input devices could accept. In the computer field, the technology trend is towards humanity and naturalization. Eye-mouse system is one way of natural human-computer interaction. The eye-mouse system version PC requires a lot of system resources, cause the PC can not handle other work well. If using multi-core parallel architecture, embedded eye-mouse system can achieve real-time control the mouse system. This paper provide a concrete realization of multi-core parallel architecture for eye-mouse system.The major work of this paper contains: finished the testing of a part of eye-mouse system’s software on DSP platform; according to the test results and related information, this paper gave up selecting DSP core, and selected high performance chip s3c2440 of Samsung as the parallel processor of the eye-mouse system; according to the demand of eye-mouse system,this paper selected a range of components to meet the system requirements in addition, including NXP’s ISP1564, Altera Corporation’s EP2C15AF484C, and so forth. Finally, based on the selected components, this paper designed the hardware reasonably. This paper designed 6 modules for eye-mouse system. These includes a main processor module, three auxiliary processor modules, a bus module and JTAG download and debug module. And completed hardware design for each module.The eye-mouse hardware system that this paper designed, can achieve handle more than 10 pictures in one second, can realize real-time control the mouse system.更多还原
