本秒表计时器用于体育竞赛及各种要求有较精确时的各领域。此计时器是用一块专用的芯片，用VHDL语言描述的。它除开关、时钟和显示功能以外，它还包括1/100s计时器所有的控制和定时功能，其体积小，携带方便。-the stopwatch timer for the various sports competitions and requires more accurate at the various fields. This timer is a dedicated chip, using the

本文介绍一种以CPLD[1]为核心、以VHDL[2]为开发工具的时间控制器，该控制器不仅具有时间功能，而且具有定时器功能，能在00：00～23：59之间任意设定开启时间和关闭时间，其设置方便、灵活，广泛应用于路灯、广告灯箱、霓虹灯等处的定时控制。-This article describes a CPLD [1] as the core, VHDL [2] for the development of tools for time controller that features not onl
