摘　　要：本文介绍一种用MCS—51汇编语言设计的单片微机系统时钟软件。该软件所需的中断服务时间短,因而不影响CPU进行其他实时性较高的处理工作,该软件还能提供时间显示功能,文中给出了相应的显示硬件结构。A software of calendar clock, used for single chip microcomputer systems (SCMCS) and designed with MCS—51 assembly language, is introduced. The run time of interruption service required for the software is short, and therefore it can meet the need for real time processing in some SCMCS. In addition, time display can also be made with the software and structure of related hardware to display is given.
