Hi,

Is there a way to reduce the size of this routine ?

Polynomial  = x0 + x12 + x17

x0 is in "data" bit_0
x12 is in "mid" bit_3
x17 is in "old" bit_0

                rlf     mid,w        ; x12 in w bit_4
                movwf   temp         ; x12 in temp bit_4
                swapf   temp,w       ; x12 in w bit_0
                xorwf   old,w        ; x12 + x17 in w bit_0
                xorwf   data,w       ; x0 + x12 + x17 in w bit_0
                movwf   temp
                rrf     temp,f       ; x0 in Carry

                rlf     new,f        ; x0 to bit_0
                rlf     mid,f        ; Updates x12
                rlf     old,f        ; Updates x17

Thanks for your help.
