俩个比较好的计数器的vhdl代码：一个是n位通用计数器，一个是的用到的语法比较全面。是比较好的学习资料...

fpga测温的框图和源码 希望能帮到大家 没有测试 紧供参考-fpga vhdl

vhdl,序列信号检测模块，此模块检测1110010，可改为任意序列，输出电位为1为检测出，否则为0-vhdl, sequence of signal detection module, this module testing 1.11001 million, can be changed to an arbitrary sequence, the output potential of an as detected, otherwise 0

一个基于FPGA用verilogHDL设计的bayer格式转RGB格式的模块，本人设计(a code used for bayer_3RGB_interpolation ,which based on FPGA by verilogHDL)

7对于进入密码锁的按键，假设复位后七个灯显示" 0"，而使用sw5、sw6 2，则只要按下并松开sw5后七个灯就显示" 5"，而只要按下并松开sw6，七个灯就正确显示值" 6

I2C的实现，可以扩展进而控制有关I2C的器件达到操作员的控制目的。(I2C implementations, can be extended further having control of the I2C device operator control purposes.)

DDS的频率转换可以以近似认为是即时的，这是因为它的相位序列在时间上是离散的，在频率控制字改变之后，要经过一个时钟周期之后才能按照新的相位增量增加，所以也可以说它的频率转换时间就是频率控制字的传输时间，-DDS frequency conversion can be considered similar to real-time, this is because it is the phase sequence in time is discrete, in the frequency control word change after one clock cycle to go through before a new phase in accordance with the incremental increase, so it can be said of the frequency switching time is the frequency control word transmission time,
