1. Then , memory cell array and some parts of peripheral circuits used in sram , for example , sense amplifyier and adderss decoder , are designed and verifyied by simulation . furthermore , some novel methods , such as clocked hierarchical word decoding structure , multi - stage sense amplifyier , common data line and data bus equlibruim technology has been applied in the design of 128kbit and imbit sram . what ' s more , we have studied compiler technology applied in the designing course of a imbit full cmos sram from the pointview of methology
   然后对sram的存储单元电路以及外围电路中的灵敏放大器和地址译码器进行了设计和模拟，在此基础上，以128kb和1mb全cmossram设计为例，从方法学角度对同步sram设计中的带时钟分等级字线译码，多级灵敏放大和位线及总线平衡等技术进行了研究，并给出了相应的compiler算法。
2. Peripheral devices in embedded systems are often connected to the mcu as memory - mapped i / o devices , using the microcontroller ' s parallel address and data bus . this results in lots of wiring on the pcb ' s to route the address and data lines , not to mention a number of address decoders and glue logic to connect everything
   由于并行总线扩展时连线过多，外围器件工作方式各异，外围器件与数据存储器混合编址等，都给单片机应用系统设计带来布线复杂，线路板面积大，易引起emi和esd干扰等困难，这在一些比较复杂的应用系统是难以接受的。
3. Although there are many literatures describing ultrasonic detector for traffic flows , none of the same category has referred the techniques applied in the design herein such as multi - sensor construction , automatically establishing datum line regardless of suspension height , digital filtering and multi - lane detection as well as measuring length of motorcade
   目前有关超声波车流检测器的文献较多，但本设计中采用的多探头结构、自动标定超声波探头的架设高度、数据滤波以及多车道测量和检测车队长度等技术在同类设计中未见使用。
4. Fully considering the system ' s reliabilty , being real - time , speed and extensibility , it finally chooses the sdh as the system network of cors through deep compration and alalysis of four special data lines supplied by china telecom , so that an effective interconnection among the stations and the workstations in the control - center comes true
   摘要充分考虑系统可靠性、实时性、通信速率、可扩充性等因素，通过对中国电信提供的4种数据专线服务的综合分析比较，选择了同步数字体系作为系统通信网络，实现了控制中心各工作站和各基准站之间的高速互联。
