0 我现在写着一个CORDIC 的 verilog 代码，但在逻辑上遇到问题。 https://www.edaplayground.com/x/3tHk ，为何 y[2] == 0 ? cordic.zip (1.01 KB, 下载次数: 3 ) --> verilog 代码 Cordic_octave.zip (482 Bytes, 下载次数: 0 ) --> octave/matlab 代码 i= 0, x=10011011011101001, y=00000000000000000, z=0000000000000000011110, d= 0, arctan=0000000000000000101101 i= 1, x=10011011011101001, y=10011011011101001, z=1111111111111111110001, d= 1, arctan=0000000000000000011011 i= 2, x=00011011011101001, y=00000000000000000, z=0000000000000000001100, d= 0, arctan=0000000000000000001110 i= 3, x=00000110110111010, y=00000110110111010, z=1111111111111111111110, d= 1, arctan=0000000000000000000111 i= 4, x=00000001101101110, y=00000000000000000, z=0000000000000000000101, d= 0, arctan=0000000000000000000100 i= 5, x=00000000000110110, y=00000000000110110, z=0000000000000000000001, d= 0, arctan=0000000000000000000010 i= 6, x=00000000000000000, y=00000000000000011, z=1111111111111111111111, d= 1, arctan=0000000000000000000001 i= 7, x=00000000000000000, y=00000000000000000, z=0000000000000000000000, d= 0, arctan=0000000000000000000000 i= 8, x=00000000000000000, y=00000000000000000, z=0000000000000000000000, d= 0, arctan=0000000000000000000000 i= 9, x=00000000000000000, y=00000000000000000, z=0000000000000000000000, d= 0, arctan=0000000000000000000000 Done 0
