FPGA在线实验平台设计与在线实验方法研究
|
摘要
针对传统FPGA (Field Programmable Gate Array,现场可编程门阵列)实验只能在本地完成的局限性,探索MOOC(Massive Open Online Course,大规模开放在线课程)在实验教学中的应用新模式,自主研发了FPGA在线实验平台。利用该平台,学生可以随时随地进行在线实验,从而突破时空限制;该平台支持以FPGA为核心的多门硬件类课程在线实验,使得多门课程衔接贯通,有助于培养提高学生的计算机系统设计能力。提出实现键盘鼠标接口在线实验和VGA实时显示的远程控制方法,解决了支持键盘、鼠标和VGA显示器的技术难题,拓展了平台功能,增加了在线实验项目的多样性和趣味性,有助于激发学生的学习兴趣和创新意识。开发的在线实验平台和在线实验方法已应用于实际教学中,并取得了很好的教学效果。
To solve the limitation that the traditional FPGA( Field Programmable Gate Array) experiments could only be done locally, a new application model of the MOOC was explored and a FPGA online experimental platform was developed independently. With this platform, students can do on-line experiments anytime and anywhere, thereby breaking through the restrictions of time and space. It supports multiple FPGA-based courses and interlinks them to each other, which helps to comprehensively improve students' capability of computer system design. At the same time, a remote control method for realizing online experiment of keyboard and mouse interface as well as VGA realtime display is proposed. In this way, the technical problems of supporting keyboard, mouse and VGA display have been solved. So it expands the functions of the platform, increases the variety and interest of the online experimental projects, and helps to stimulate students' interest in learning and innovation. The developed online experimental platform and teaching method have been applied in practical teaching and have achieved good teaching results.
