音乐计算器的设计与实现。完成加减与或比较计算，能显示进位借位零位，能根据结果的正负发出两首不同的音乐。(Design and implementation of music calculator. Complete addition and subtraction and comparison calculation, can display carry and borrow zero, can send out two different music according to the positive and negative results.)

数字密码引爆器的输入描述：1、 在开始输入密码以前的等待状态，首先要按READY键，表示目前准备就绪，可以输入数字密码；2、 当引爆事件发生后，应该回到等待状态，设置WAIT_T键；3、 如果输入密码不正确，此时要操作READY和WAIT_T是不起作用的，必须由设计人员重新设置到等待状态，设置SETUP键，SETUP为内部按键，操作人员应该不能接触；4、 确定密码输入后，要设计一个点火按键FIRE；-digit passwords detonated"s input Description : one at the start and enter the password before the wait state, according to First READY button, now ready to be imported into digital code; Two, when detonated after the incident, should wait for the state to set up WAIT_T bond; three, if a password is not correct, this time to operate READY WAIT_T and is non-functional, the design must be re-installed to wait for the state, set up SETUP button SETUP internal keys, the operator should not contact; 4 to determine the password, to design a FIRE- ignition keys;

基于DDS和SOPC的谐波信号发射器，拥有可调节的频率，阶段和谐波比例的谐波信号发射器由本文所设计。(Based on DDS and SOPC harmonic signal transmitter, with adjustable frequency, phase and harmonic proportion of harmonic signal transmitter designed by this article.)

Rst是低电平有效的系统复位信号，Clk是时钟信号。AB[5：0]是地址信号，DB[7：0]是数据信号，wr是低电平有效的写信号。start是启动信号。 模块中有一个64x8的双端口的存储器。系统复位结束后，可以通过AB、DB和wr信号向同步存储器写入数据。当写入64个数据后，给出一个Clk周期宽度的脉冲信号start，则系统从存储器0地址处开始读出数据，读出的8位数据从低位开始以3位为一组，每个时钟周期输出一组，即第一个时钟周期输出[2：0]位，第二个时钟周期输出[5：3]位，第三个周期输出1地址的[0]位和0地址的[7：6]位，直至将存储器中64x8数据全部输出。若最后一组不足三位，则高位补0。 (Rst is an active-low system reset signal, Clk is a clock signal. AB [5: 0] is the address signal, DB [7: 0] is the data signal, wr write signal is active low. start is the start signal. Module in a dual port memory of 64x8. After the reset, you can write data to the synchronous memory by AB, DB and wr signals. When data is written to 64, given the width of a pulse signal Clk cycle start, the system begins to read the memory address 0, 8 data read out a low starting with three as a group, each clock outputs a set period, which is the first clock cycle of the output [2: 0] bits, the second clock cycle output [5: 3] position, the third cycle of the output of an address [0] and 0 address [7 : 6] bit, until all the data in memory 64x8 output. If the last group of less than three, the high 0s.)
