利用FPGA实现SDRAM的读写操作，通过硬件测试。(FPGA implementation using SDRAM to read and write operation, hardware testing.)

应用布莱克曼窗实现FIR滤波器，并绘制相应波形图案(Application Blackman window FIR filter, and draw the corresponding waveform pattern)

1、PC和寄存器组使用时钟触发。 2、指令存储器和数据存储器存储单元宽度一律使用8位，即一个字节的存储单位。 3、控制器部分可以考虑用控制信号真值表方法（有共性部分）与用case语句方法逐个产生各指令其它控制信号相配合，注意：信号必须与状态配合。。当然，还可以用其它方法，自己考虑。 4、试用的汇编程序，而且必须包含所要求的所有指令。Slt、sltu指令必须检查两种情况：“小于”和“大于等于”；beq、bne指令必须检查两种情况：“等”和“不等”。这段汇编程序必须尽量优化，同时，给出每条指令在内存中的地址。(1, PC and register groups are clocked. 2, the command memory and data memory storage unit width will use 8 bits, that is, a byte storage unit. 3, the controller part can be considered with the control signal truth table method (common part) and with the case statement method to produce each command other control signal match, Note: the signal must be with the state. The Of course, you can also use other methods to consider their own. 4, try the assembler, and must contain all the required instructions. Slt, sltu instruction must check two cases: "less than" and "greater than or equal to"; beq, bne instruction must check two cases: "wait" and "unequal". This assembler must be optimized as much as possible, giving the address of each instruction in memory.)

FIR带通、带阻滤波器设计，需要输入截止频率以及容许偏差。(FIR band pass and band stop filter design)

自己做的数码管显示的时钟 一个非常简单的FPGA时钟 用累加做的(To do their own digital display clock of the FPGA clock is a very simple to do with the cumulative)

说明：  da的代码,在VHDL的编译环境下的开发。是一种集约的形式。(DA convert)

说明：  为串口收发器以及汉明编码，将电脑通过串口发送的7位数据转化成汉明码显示于led上，或把接收到的11位汉明码解码并验错纠错(For the serial port transceiver, and Hamming codes, the computer through the serial port into 7-bit data displayed on the led on the Hamming code, or to receive the 11 Hamming code error correction decoding and experience)

实现了从摄像头读取数据到液晶的显示，利用了cycloneV 和康欣的开发板资源(It realizes the display of reading data from camera to liquid crystal.)
