Design principles and realization of high-speed data acquisition system control module based on cpld technology 的高速数据采集系统控制模块的设计与实现
4 . dynamic signal process system is made up of system self test module system control module the general signal process auto generate report module diagnose and error process module 动态信号分析部分,由系统自检模块、系统控制模块、信号处理模块、报告自动生成模块、诊断与错误处理模块等软件模块组成。
Modular design is adopted in digital modulation system . in this way digital modulation system consist of vedio process module, synchronized drive module, semiconductor laser modulation and system control module 数字化调制系统采用模块化设计方法,把系统分为四个功能模块,即视频信号处理、同步驱动、半导体激光调制和系统控制模块。
system control module accomplishes many functions, such as systemic initialization, controling work of the system, man-machine interface and selecting channel . it communicates with other modules by i2c bus . timing signals are inputed into microprocessor through p1 port and control signals are provided through p2 port 系统控制模块和其他模块间的通讯基于i~2c总线,并利用了p1口进行各时钟信号的检测和利用p2口的各线作为控制线宋控制相应模块的工作。
A system design of the circulation function therapeutic instrument of brain is presented in this paper . an integrated prototype is composed of at89c55 used as system controlling module and a / d, d / a converter and liquid crystal display device used as a terminal display module to realize the output of dynamic load and permanent flow through digital synthesis 本文提出了一种设计智能脑电治疗仪的系统方案,以at89c55为核心控制模块,辅以d/a、a/d成为全反馈闭环系统,使用液晶显示器为终端显示设备,实现数字合成动态负载恒流输出。
