8位十六进制频率计设计 根据频率的定义和频率测量的基本原理，测定信号的频率必须有一个脉宽为1s的输入信号脉冲计数允许信号；1s计数结束后，计数值被锁入锁存器，计数器清零，为下一测频计数周期做好准备。测频控制信号可由一个独立的发生器（FTCTRL）来产生。-8-bit hexadecimal Cymometer designed in accordance with the definition of frequency and frequency of the basic principles of measurement to determine the frequency of the signal must have a pulse width of the input signal for 1s permit pulse counting signal 1s counting after the total value was locked into the lock depositors, counters cleared for the next count cycle frequency measurement ready. Frequency control signal generator may be an independent (FTCTRL) to generate.

dct1d核心的FPGA实现
应用背景为了实现良好的压缩性能，相关性颜色分量RGB颜色空间转换到去相关的色彩空间首先减少。在基线JPEG，一个RGB图像转化成亮度chrominancc如YCbCr颜色空间。将图像的亮度色度空间的优势的亮度和色度分量非常不相关彼此之间。此外，色度通道包含大量冗余信息可以很容易地被采样不牺牲任何视觉质量对于重建图像。从RGB到YCbCr的转换，是基于以下的数学表达：关键技术应用DCT变换，将图像划分成8´8像素块。如果原始图像的宽度或高度是不能被8整除，编码器必须整除。8´8块进行处理，从左到右，从上到下。和公司；及；及；及；及；及；及；及；及；DCT变换的像素值的空间频率。这些空间频率是非常相关的细节目前在一个图像的水平。高空间频率对应于高层次的细节，而较低频率对应于较低的细节层次。数学定义DCT是：

Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.
