基于fpga的mcs-51单片机的定时模块设计毕业设计

摘 要随着计算机技术的进展，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。但随着社会的进展，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进展越来越成熟，为单片机的进展开辟了新的途径，为单片机的设计与升级提供了一种新的方法。本文采纳的是以 FPGA 器件为载体，采纳 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 Quartus II 为设计平台，经过编译、调试、修改、仿真测试，完成该设计。本课题讨论表明，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、更高效的进展趋势。关键词：MCS-51 单片机，VHDL，EDA，FPGA，TOP-DOWNAbstractAlong with calculator technique of development, list the slice's machine technique have already become a calculator technique in of independence branch, and because of its oneself have of superiority(cleverly made and vivid, control the ability be strong, the cost be low, be easy to a product to turn...etc.), make it at society of each the realm get extensive of application, with our life close connect with each other, especially have in the industry the control and the appearance instrument intelligence turn and it importance of function.But along with the development of society, list slice machine also existence-some irregularity, it speed, scale, function etc. the index sign be more and more hard satisfy the customer's need, so list slice machine of development, get stripe to face new of challenge.Along with programmable logic controller technique of development more and more mature, for list slice machine ...
