I am just giving a general hint, should be applicable to your case also
after some changes

What you do is to tap the x7 and x4 bit of polynomial and XOR it with the
bit 0 of incoming data stream. The xored value is your output bit 0. Then
DEPENDING upon the protocol, you may either push in the output bit to msb
position of polynomail and shift all other bits of polynomial either right
or left depending upon your direction convention.

Repeat the above process each input bit....
