CRC16 with 4-bit input

[Jaiphen]

Does any know how to implement CRC16 generator with 4-bit data input?
I am thinking to implement it with some combinational logic instead of
store the info in a table. Thanks!

Write a function that implements the 1 bit transformation crc =
1bit_gen( crc , i0);
Then call it 4 times: crc =
1bit_gen( 1bit_gen( 1bit_gen( 1bit_gen( crc , i3) , i2) , i1) , i0);
