这篇是利用VHDL语言控制LCD1602芯片来显示时钟的简单代码。LCD1602顾名思义是一种02*16，即为两行十六列的液晶显示屏，液晶两行，每行可以显示16个字符，但是CGRAM及CGROM里面一共有160个字符，包括阿拉伯数字，英文字母大小写，常用符号及日文。每个字符对应于一个ASCII码值，在液晶显示屏上显示对应的字符时候，只需要将对应的ASCII码写到DDRAM中就好。

The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.

This code that genetes a square, sawtooth and a triangular waveform. It is useful for designing a function generator in VHDL.
