NIOSII的液晶显示ip 核，含有所有底层源代码-Ip of the liquid crystal display NIOSII nuclear, containing all underlying source code

Part I We wish to display on the 7-segment displays HEX3 to HEX0 the values set by the switches SW15−0. Let the values denoted by SW15−12, SW11−8, SW7−4 and SW3−0 be displayed on HEX3, HEX2, HEX1 and HEX0, respectively. Your circuit should be able to display the digits from 0 to 9, and should treat the valuations 1010 to 1111 as don’t-cares. 1. Create a new project which will be used to implement the desired circuit on the Altera DE2 board. The intent of this exercise is to manually derive the logic functions needed for the 7-segment displays. You should use only simple VHDL assignment statements in your code and specify e

采用一个标准的基准时钟，在单位时间如1S里对被测信号的脉冲数进行计数，即为信号的频率，由于闸门的起始和结束时刻对于信号来说是随机的，将会有脉冲周期的量化误差，进一步分析测量准确度。因此直接测频法只适合测量频率较高的信号，不能满足在整个测量频段内的测量精度保持不变的要求。若要得到整个频段内较高的精确度，应该考虑等精度测量等其他方法。
