cordic算法，实现加减乘除、幂次方、开方的运算(CORDIC algorithm implementation, power add, subtract, multiply and divide and square root operations)

基于fpga的电子血压计。pdf文档，好用，内容清楚简单，转载而来(Electronic sphygmomanometer based on fpga)

按照手册驱动线阵CCDTCD1209和AD9945，驱动频率10M，板卡时钟30MHz，经PLL分频后输入驱动，该程序在altera cyclone IVE上验证通过

基于FPGA的用verilog语言写的，改程序可产生不同调制系数和不同频率的AM波，长按按键切换调制度25 、50 、75 和短按按键切换调制信号频率1k、1.5k、2k、2.5k.(Based on the FPGA using verilog language, change the program can produce different coefficients and different frequency modulated AM wave, long press the button to switch the modulation of 25 , 50 , 75 and short press button to switch the modulation signal frequency 1k, 1.5k, 2k, 2.5k.)

JK触发器，基于verilog编写，JK触发器和触发器中最基本的RS触发器结构相似，其区别在于，RS触发器不允许R与S同时为1，而JK触发器允许J与K同时为1。当J与K同时变为1的同时，输出的值状态会反转。也就是说，原来是0的话，变成1；原来是1的话，变成0。

AES加密算法verilog源码 This project is the hardware implementation of the  Advanced Encryption Standard with a key size of 128 bits. The implementation adheres to the FIPS-197 document which explains the same.The core can do both encryption as well as decryption.The documents aes_arch.doc and aes_tb_readme.txt give further details of the rtl implementation and test bench respectively. This code was written originally with 128 bit ports for both input and key but later converted to 64 bits each to save on i/o pins. It can be reverted back easily if one just changes the port widths and dispenses with the load signal in the top module and making approriate changes in process where load is used.Synthesis results have been included for Xilinx Spartan-3 device.The directory structure of the project is as under- AES128
