摘要
智能温室是近年逐步发展起来的一种资源节约型高效农业发展技术,目前国内大多以单片机、通用计算机作为温室系统处理器,由于基于单因子和成本问题,其智能化和效率有待提高。在此通过对目前智能温室控制器的分析研究,提出并设计了一款16位的的单总线专用CPU,且专门针对于智能温室测控系统设计了一个浮点运算器和n个Comparray比较器,并使用VHDL语言在QuartusⅡ6.0中进行设计与仿真。所以,该CPU不但具有通用CPU的基本特性,而且更具有在农业温室控制系统领域的特殊性。
The intelligent greenhouse is a resource-saving efficient agriculture technology developed gradually in recent years.Nowadays,the single-chip microcomputer or general computer is used as a processor for most of the greenhouse control systems,but their intelligentization and efficiency need to be further improved because of single factor and high cost.A 16-bit single bus dedicated CPU is designed in this paper based on the research and analysis of the commonly-used intelligent greenhouse controllers.A floating point unit and Comparray comparator are developed for the dedicated CPU.The design and simulation were done with VHDL in Quartus Ⅱ 6.0.Therefore,the CPU not only has the basic characteristics of general CPU,but also possesses the particularity of agricultural greenhouse control system.
