屏幕上不停地出现随机（随机颜色，随机边长，随机线宽）的三角形(Constantly appear on the screen randomly (random color, random side, random width) of the triangle)

FPGA可实现的，使用cordic算法的NCO模块混频模块。该模块基于cordic原理，算法中只需要加法和移位运算既可以完成信号的混频功能(FPGA can be achieved, the use of the NCO cordic algorithm module mixing module. Cordic module based on the principle, the algorithm only needs Adder and shift operator can complete signal mixing function)
