build_crc32_table.m

CRC编码的基本实现

function CRC32_Table = Build_CRC32_Table(g_x)

CRC32_Table = [];
for i=1:256
    in = [de2bi(i-1,8,'left-msb') zeros(1,32)];
    for j=1:8
       in(j:j+32) = bitxor(in(j:j+32),in(j)*g_x);        
    end
    in = reshape(in(9:end),8,4)';
    CRC32_Table(i,:) = bi2de(in(1:4,:),'left-msb')';
end
