An approach to design small scale CMOS static random access memory (SRAM) is proposed. The design of address decoder, memory cell, and the layout are included. This approach adopts flip-flop array structure.The flip-flops are used as the storage cells and they are stacked to form the whole SRAM module. The word select bit is generated from the address decoder. And one word at a time is selected for reading or writing. The design of the memory core‘s layout is also discussed since it should be optimized to save area and also should be convenient for realization. It‘s a full-custom layout. The address decoder is composed of combinational logic circuit and its layout is also designed as a full-custom layout. With all these modules, the integral structure of the SRAM is cartied out. 相似文献

动态系统的自适应模糊神经网络控制 总被引:1,自引:0,他引:1
Aim To build an adaptive fuzzy neural controller and simulate
it. Methods Fuzzy logic and back propagation(BP) algorithm are combined
to utilize their advantages while avoiding the disadvantages. Results and
Conclusion Simulation results of the third-order plant with disturbances and dead
times show the validity of the presented controller. The presented controller can control
cases that preceding controllers were unable to control. 相似文献

一种双精度浮点乘法器的设计 总被引:2,自引:0,他引:2
设计了一个双精度浮点乘法器。该器件采用改进的BOOTH算法产生部分积,用阵列和树的混合结构实现对部分积的相加,同时,还采用了快速的四舍五入算法,以提高乘法器的性能。把设计的乘法器分为4级流水线,用FPGA进行了仿真验证,结果正确;并对FPGA实现的时序结果进行了分析。 相似文献

针对一类坐标非耦合的目标运动模型分析转换测量Kalman滤波的渐近特性.基于转换测量误差协方差矩阵的特征值分解,给出了转换位置测量的时间渐近特性.作为分析的附带结果,给出了一种新的序贯滤波算法.提出了准一致完全可观测性的概念并利用这一概念分析了滤波器估计误差的协方差界限和偏差特性.分析表明,滤波器的发散是潜在的甚至是不可避免的,特别是目标快速远离传感器时.这正是由于该系统并不是一致完全可观测的而是准一致完全可观测的.最后,不同的蒙特卡罗仿真验证了上述理论分析的结果. 相似文献
