Examples
- Chapter two detailedly presents the design of the boundary scan testing system which is in accordance with ieee . 1149 . correspondingly two special - used data registers are added , one of which is the scanning chain register and the other is the child scanning chain control - register
文中第二章按照ieee . 1149标准详细设计了边缘扫描测试系统，相应增加了两个专用数据寄存器，其中一个为扫描链寄存器，一个为扫描子链控制寄存器。 - Then a comparison is made according to their characters and the application scope of each method is determinate . from that we get the whole scheme of design for testability of dspc50 , which is using boundary scan to improve the board - level testability of the chip and using full - scan in designing the nuclear circuit to reduce the difficulty of testing the chip
在此基础上得到dspc50的可测性设计的整体方案，即采用边缘扫描设计提高芯片在板级的可测性，同时用全扫描思想设计芯片核心电路，以降低芯片本身测试的难度，即将芯片的全扫描设计包含入边缘扫描系统。 - From the view point of the foundation of dft ( which includes the testable measure of gate - level circuits , the testable and controllable measure of functional - level , the flow and methodology of dft and so on ) , the author introduce some common testing technology such as scan and bist in modern times . especially the boundary scan technology has been widely adopted in the dft of vlsi . with the special controller , the testing vector could be scanned to the corresponding ports of inner cores from the testing input ports , and the response could also be shifted to the testing output ports
本文从可测性设计的基础理论出发（包括门级电路的可测性测度、功能级上的可测性和可控性、可测性设计的流程和方法等） ，介绍了现代常用的可测性技术，比如：扫描技术、内嵌自测试技术等，特别是边缘扫描技术已经广泛地应用到vlsi的可测性设计之中，它通过特定的控制器，从相应的测试输入端口将测试向量扫描至芯核所对应的管脚，再将结果从相应的测试输出端口扫出。 - Under natural environment , the plate character can be faint or transfigured . as a result , we bring up several algorithms to process the noise in the image , including single point noise processing algorithm , noise processing methods based on connected area , second - moment and edge scanning , which are efficient in getting rid of the noise
本文根据自然条件下车牌字符模糊,变形等特点,提出了多种图像噪声处理的算法,包括单象素噪声去除算法,基于连通域和二阶矩以及边缘扫描的噪声去除算法,较好的去除了图像中包含的噪声区域。
