Description: 此實驗中我們將量 測人的反應時間，由於人的反應時間遠比起內建CLOCK的週
期長的多，因此要對CLOCK做除頻的動作方可適用，並方便 於計數 器的計算與
七段顯示器的呈現。實驗內容為，當看到LED亮 起時，立 即做出反應將計數 器停
下，並顯示出當時計數 器之時間。計數 器以兩 位數 BCD counter來 實現並將結果
顯示於七段顯示器上。-Volume in this experiment we will test people' s reaction time, because people' s reaction time is far longer than the built-in multi-CLOCK cycle, and therefore the frequency of CLOCK to do except be applicable to the action, and facilitate in the total number of device Computing and seven-segment display rendering. Test content, when you see LED Leung from time to time, to respond immediately to stop the total number of devices and demonstrate the total number of devices was the time. Total number of devices with two-bit number of BCD counter future to achieve the results shown in the seven-segment display.

Description: 当按一次按健时，由于按健有反应时间、有抖动，可能你按一次机器感应到几次，防抖就是让在按键正常反应时间内机器只感应一次按键效果，防止误操作，本文是基于FPGA的按键防抖程序代码，用的是VHDL语言，内容包括原理，实际操作及源码等。-When you press a pressing health, because according to health have reaction time, jitter, you may press machine senses a few times, image stabilization in the key is to let the normal reaction time machine button only once induced effects, to prevent misuse, the paper is key FPGA-based image stabilization program code, using VHDL language, including theory, practice and source code, etc.
