主机通信

• Since each host must be able to communicate with each other host in the db2 udb dpf instance , set up your shosts . equiv file such that it can be reused on all hosts
  由于每个主机必须能够与db2 udb dpf实例中的所有其他主机通信，所以设置shosts . equiv文件，使之能够在所有主机上重用。
• The reliability of non - central - switching system is more high than that of switching system because the communication process of non - central - switching system is not depend on switcher
  相对于有主机通信系统来说，这种无主机系统的通信过程不依赖于主机，因此，无主机系统具有更高的可靠性。
• The middleware development team provided additional performance metrics to isolate the elapsed time for host communication , message parsing , and the middleware elapsed time for transaction processing
  中间件开发团队提供另外的性能度量，将用于主机通信、消息分析的耗用时间与用于事务处理的中间件耗用时间隔离开来。
• This paper mainly introduces the hardware and software design and debug of usb2 . 0 interface between the host computer and the film scanner , and give prominence to the advantage of this project
  本文主要论述了胶片扫描仪与主机通信的usb2 . 0接口的硬件设计、软件设计以及调试的整个方案，以及突出了这种方案的优越性。
• On the hardware part , there are six modular , the power modular , and the iris image capture system , the iris image processing modular , the system memory space , the lcd and keyboard design , and the usb2 . 0 interface
  硬件方面由六个模块组成,分别是电源监控管理及复位、虹膜图像采集、虹膜图像处理、系统存储器、人机交互以及usb2 . 0主机通信数据传输接口等。
• Eddy - current sensor conversion circuit consist amplification circuit , band - pass filter circuit , demodulation circuit , differentiation phase and data sampling circuit . these circuits are used to convert the test signal of eddy - current sensor to discrete signal tend to process . the microprocessor system that formed of dsp chip is used to data fitting of test system , data displaying and data communicating with personal computer , etc . the interference questions of hardware design and the measure of eliminating interference signal in the subject are introduced in the last of this chapter
  硬件电路的设计主要分三大部分来实现：激励源电路部分，由分频电路和频率合成电路组成，产生频率稳定的激励信号以确保检测任务的正常进行；传感器变换电路部分，由放大电路、滤波电路、检波电路、鉴相电路和数据采集电路组成，主要将电涡流传感器检测线圈检测到的信号变换成只含有被测信息的离散信号，易于后续电路处理；由dsp芯片构成的微处理系统，主要完成检测系统的数据拟合、显示及与主机通信等功能。
• At last , the thesis studies the communication mode of pmac , including the analysis of the communication method between pmac and dpr , the communication method between pmac and host computer , and the analysis of the communication method between upper computers and lower computers , and the uses the visual c + + 6 . 0 to exploit the upper computer software base the characters of communication methods
  最后对pmac的通信方式进行了分析,分析了pmac与dpr通信的方式, pmac与主机通信的方式,以及其上位机和下位机通信原理,并根据其通信方式特点利用visualc + + 6 . 0对五杆机构控制系统作了开发。
• In the process of designing hardware , the principal and subordinate structure is adopted : the principal cpu accomplishes the communication with the group host computer ; the subordinate cpus accomplish the communication with some command post computers and observe post computers ; the principal and subordinate cpus exchange data through parallel bus to realize the communication between the group host computer and its subordinate computers
  在硬件系统设计中，采用了主从结构：主cpu完成与群主机通信，从cpu完成与各指挥所、观察所计算机通信，再通过主从cpu间并行总线的数据交换来完成群主机与其下属计算机的通信。
• Lcd with touch screen offers human - computer interface , the communication between auto palm and main controller is completed by uart port . the core of the main controller is at89c51 , one external 64m 8bits sdram is used for data and program . i / o ports of the microcontroller connect to the adapter through fpga
  Lcd和触摸屏作为人机交互界面, uart通信端口与主机通信;主机硬件是以at89c51作为核心,外扩64m 8bit的sdram作为外部程序空间和数据空间,单片机i / o口均通过fpga连接到适配器端,通过适配器实现通信协议的转换,对汽车电控单元进行检测与维修。
