Description: 今天看了一下从fpga上下的曼彻斯特编解码的程序，感觉不是很清楚，仿真了一下，更迷茫了，大家看看为啥这程序要这么编呢？
程序比较长，不过写的应该还是不错的，看了后应该有收获。
总的思路是这样：
1 通过一个高频的时钟检测wrn信号，如果检测到上升沿，则表明开始编码，将输入的8位数据转为串行，并编码，然后输出。
2 定时信号是从高频时钟16分频后得到的，在wrn上升沿后16分频使能，在编码结束后禁止分频输出。
3 no_bits_sent记录串行输出的位数，应该是从0010到1001输出串行信号，到1010时编码结束，输出tbre表明编码完成。
问题是no_bits_sent在到了1010后还是会继续增加，直到1111，然后clk1x_enable 就为0，无法分频，clk1x就为一直流信号。这样当clk1x_enable再次为1的时候，no_bits_sent也不会增加，在1111上不变，clk1x_enable又会回到0了。
-today they simply watched from across the Manchester encoding and decoding process, not feeling very well, simulation a bit more confused, we look at procedures to be ready this series so? Procedures longer, but should still write good, it should have read harvest. The thinking is this : one by a high-frequency clock signal detection international, if detected rising edge, it indicates the beginning of coding will be entered into the eight to serial data and coding, and then output. Two timing signals from the high-frequency clock frequency 16 hours after the the international rising edge after 16 minutes frequency to enable the coding after the end of Prohibition-frequency output. 3 no_bits_sent record median serial output, it should be from 0010 to 1001 serial output signal to the end of Platform: |

Description: 平滑滤波 一般来说，图像的能量主要集中在其低频部分，噪声所在的频段主要在高频段，同时系统中所要提取的汽车边缘信息也主要集中在其高频部分，因此，如何去掉高频干扰又同时保持边缘信息，是我们研究的内容。为了去除噪声，有必要对图像进行平滑，可以采用低通滤波的方法去除高频干扰。图像平滑包括空域法和频域法两大类，在空域法中，图像平滑的常用方法是采用均值滤波或中值滤波，对于均值滤波，它是用一个有奇数点的滑动窗口在图像上滑动，将窗口中心点对应的图像像素点的灰度值用窗口内的各个点的灰度值的平均值代替，如果滑动窗口规定了在取均值过程中窗口各个像素点所占的权重，也就是各个像素点的系数，这时候就称为加权均值滤波；对于中值滤波，对应的像素点的灰度值用窗口内的中间值代替。实现均值或中值滤波时，为了简便编程工作，可以定义一个n*n的模板数组。另外，读者需要注意一点，在用窗口扫描图像过程中，对于图像的四个边缘的像素点，可以不处理；也可以用灰度值为\"0\"的像素点扩展图像的边缘。下面给出了采用加权均值滤波的图像平滑函数代码和效果图：-smoothing filter general, the image of energy is mainly focused on the low-frequency part of the noise lies mainly in the high-frequency band, which system to extract the vehicle Edge Information has been concentrated in some of its high frequency, therefore, how to remove high-frequency interference at the same time, maintain the edge information, we Institute enforcement of the content. In order to remove noise, it is necessary for smooth images can be used to the low-pass filter to remove high-frequency interference.
