ALU用VHDL项目

Fpga开发应用，jtag方面的源代码，VHDL-Fpga development and application, jtag in the source code, VHDL

EDA中很重要的小程序，保证按键可靠性，防止抖动误差信号产生，外部信号输入时必用此消抖函数-EDA very important small procedures to ensure that key reliability and prevent jitter error signal generated, the external input signal must use this function Consumers shiver

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;

：采用FPGA来实现一个基于OFDM技术的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制器包括：信道编码（Reed-Solomon编码），交织，星座映射，FFT和插入循环前缀等模块。我另外制作了相应的解调器，可以实现上述功能的逆变换。-: Using FPGA to implement a technology-based OFDM communication systems in base-band data processing part of the modem. One part of the modulator launch include: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and cyclic prefix insertion modules. I also produced a corresponding demodulator can achieve the above-mentioned inverse transform function.
