TLV1544与TMS320VC5402通过串行口连接,此时,A/D转换芯片作为从设备,DSP提供帧同步和输入/输出时钟信号。TLV1544与DSP之间数据交换的时序图如图3所示。 开始时, 为高电平(芯片处于非激活状态),DATA IN和I/OCLK无效,DATAOUT处于高阻状态。当串行接口使CS变低(激活),芯片开始工作,I/OCLK和DATAIN能使DATA OUT不再处于高阻状态。DSP通过I/OCLK引脚提供输入/输出时钟8序列,当由DSP提供的帧同步脉冲到来后,芯片从DATA IN接收4 b通道选择地址,同时从DATAOUT送出的前一次转换的结果,由DSP串行接收。I/OCLK接收DSP送出的输入序列长度为10~16个时钟周期。前4个有效时钟周期,将从DATAIN输入的4 b输入数据装载到输入数据寄存器,选择所需的模拟通道。接下来的6个时钟周期提供模拟输入采样的控制时间。模拟输入的采样在前10个I/O时钟序列后停止。第10个时钟沿(确切的I/O时钟边缘,即上升沿或下降沿,取决于操作的模式选择)将EOC变低,转换开始。

ICP fit points in data to the points in model. Fit with respect to minimize the sum of square errors with the closest model points and data points. Ordinary usage: [R, T] = icp(model,data) INPUT: model - matrix with model points, data - matrix with data points, OUTPUT: R - rotation matrix and T - translation vector accordingly so newdata = R*data + T . newdata are transformed data points to fit model see help icp for more information

The neuro-fuzzy software for identification and data analysis has been implemented in the MATLAB language ver. 4.2. The software trains a fuzzy architecture, inspired to Takagi-Sugeno approach, on the basis of a training set of N (single) output-(multi) input samples. The returned model has the form 1) if input1 is A11 and input 2 is A12 then output =f1(input1,input2) 2) if input1 is A21 and input 2 is A22 then output =f2(input1,input2) 看不懂,据高手说,非常有用。

正整数x 的约数是能整除x 的正整数。正整数x 的约数个数记为div(x)。例如,1,2,5,10 都是正整数10 的约数,且div(10)=4。设a 和b 是2 个正整数,a≤b,找出a 和b之间约数个数最多的数x。 对于给定的2 个正整数a≤b,编程计算a 和b 之间约数个数最多的数。 数据输入 输入数据由文件名为input.txt的文本文件提供。文件的第1 行有2 个正整数a和b。 结果输出 程序运行结束时,若找到的a 和b 之间约数个数最多的数是x,将div(x)输出到文件output.txt中。 输入文件示例 输出文件示例 input.txt output.txt 1 36 9

Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.
