1、基于FPGA的MCS-51单片机的定时模块设计摘要随着计算机技术的发展,单片机技术已经成为计算机技术中的独立分支,并且由于其自身具有的优越性(小巧灵活、控制能力强、成本低、易于产品化等),使其在社会的各个领域得到了广泛的应用,与我们的生活紧密相连,特别是在工业控制和仪表仪器智能化中起着及其重要的作用。但随着社会的发展,单片机也存在一些弊端,其速度、规模、性能等指标越来越难以满足用户的需求,因此单片机的开发、升级面临着新的挑战。随着可编程逻辑控制器技术的发展越来越成熟,为单片机的发展开辟了新的途径,为单片机的设计与升级提供了一种新的方法。本文采用的是以FP
2、GA器件为载体,采用EDA设计中TOP-DOWN和模块化设计思想进行系统设计,灵活运用VHDL描述语言对设计对象进行编程,来实现MCS-51单片机的定时、控制模块设计。最后以EDA开发软件QuartusII为设计平台,经过编译、调试、修改、仿真测试,完成该设计。本课题研究表明,应用EDA技术实现单片机的结构设计发放时完全可行的,并符合单片机更快速、更高效的发展趋势。关键词:MCS-51单片机,VHDL,EDA,FPGA,TOP-DOWN44基于FPGA的MCS-51单片机的定时模块设计AbstractAlongwithcalculatortechniqu
