用窗函数法设计一个线性相位FIR数字低通滤波器，用理想低通滤波器作为逼近滤波器，通带截止频率为0.2 ，阻带截止频率为0.4 ，阻带衰减不小于-40dB。(Window function method to design a linear phase FIR digital low-pass filter, as an ideal low-pass filter for approximation filter passband cutoff frequency of 0.2 stopband cutoff frequency of 0.4, the stop-band attenuation of less than-40dB.)

通过总结当前对处理器架构的安全性能的处理方法，提出一种增强DSP处理器安全性能的方法。主要从并行性方面进行了改进。最后对改进的方法进行了仿真和结果分析。(By summing up the current security architecture of the processor performance approach, a DSP processor to enhance the safety performance of the method. Mainly from the aspects of parallelism to improve. Finally, improved methods and results of simulation analysis.)

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。
