The dissertation discusses about field multi - channel nuclear data collecting system based on mcu in detail . the data collecting system adopts mcu ( micro - control units ) at89c55 as controlling core , applying high speed and low power adcs ( analog - to - digital converters ) cmos chip max 191 and 320x240 matrix graphic lcd ( liquid crystal display ) 该系统在硬件上以单片机at89c55为控制核心，以高速低功耗的a d芯片max191作为多道脉冲幅度分析器的模数转换器件，以320 240点阵图形液晶显示屏作为系统的显示器，根据初步的性能测试，系统已经达到预期的设计目标。
First of all , because rf circuit has large numbers of passive devices , especially for integrated inductor in si cmos technology , not only take big area on cmos chips , but also has notable parasitic effect , its quality factor is far lower than separated inductor , thus greatly impacts the performance of rf circuits 首先,针对rf电路含有大量无源元件的特点,特别是sicmos工艺条件下的片上集成电感,不但占用大量的芯片面积,而且寄生效应影响显著,其品质因数远低于分立元件电感,而集成电感的品质特性极大地左右了电路的性能。
For example , because of the limit of their cmos chip performances and the capability of their memorizers , this kind of balancing instruments based on singlechip machine are not fit for large digital operations in signal processing , and have difficult in test faint signal of vibration , and their expansibility are not good 例如单片机类型的动平衡仪器，因其主芯片性能和存储器容量的限制，对于信号处理的大量数字运算能力不强，小振动信号的测试性能不佳，系统功能的可扩展性有限。
Combined with the request of current emission regulation and fuel qualify , we analysis the ecu technology and the real environment of 465q engine , then designed the hardware and software of the fuel injection of the ecu with the 80c196kb of intel as the main cmos chip . drawed the hardware circuit with the protel software and designed the asm software proceeding etc . 我们结合我国当前排放法规的要求和燃油品质的现状，分析了汽油机电控技术和465q发动机的具体情况，主要以intel的80c196kb单片机为主芯片，设计了喷油控制系统的软件和硬件，利用protel电路设计软件绘制了硬件电路图和intel汇编语言设计了包括喷油主程序、脉宽计算程序、 a / d转换程序和转速计算程序在内的汇编软件。
Using the knowledge of single chip processor and integrated circuit to control cmos chip rtl8019as of network card , this paper successfully realizes ethernet communication about three phase electromotor . my research includes mainly hardware and software . hardware includes network card , isa bus interface and network reset . softwre includes tcp / ip protocol . as a result , three phase electromotor is controlled by ethernet 其中硬件的工作包括，网卡的选择，网卡的复位， isa总线接口的连接以及网关的设置。在软件方面主要的工作有tcp / ip协议的编写，其中主要包括udp 、 ip 、 arp等几个主要协议的编写。
After introducing characteristic and hardware structure of dsp , 1 decide to adopt current excellent performance integrate dsp and its tap system ; after i know this , this paper present a software and hardware scheme which is based on fault signal " data acquisition and processing by using advanced dsp technology , and in arithmetic aspect , a dsp based real - time digital filter comes true . this simplifies the system design and improves the stability and real - time property of data acquisition . adopting a dsp integrate plank ( including a dsp cmos chip and external storages ) and using software to manage and prepare entire system can improve greatly the extension , maintenance and common of the application system 在阐述了dsp的硬件结构及特点之后，结合本课题的研究方向，本文决定采用目前最高性能的dsp集成板及其开发系统，并在了解此集成板的硬件结构和开发环境的基础上，提出了利用先进的dsp技术来实现故障信号的采集与处理的软硬设计方案，并从算法方面实现了dsp的实时数字滤波，简化了测试系统的设计，提高了测试仪器的实时性；而采用dsp板卡(上面含有一个dsp芯片及外存) ，通过软件对整个系统进行调配和管理，可以极大地提高应用系统的可扩展件、可维护件及通用性。
