That is extremely clever (how did you come up with it?), but definitely needs more than 3 instructions (you need at least 2 just to shift the constant): mov eax, 0x2020c6 shr eax, cl mov cl, al shl eax, cl shr eax, 27 Yet those 14 bytes definitely beats my first attempt... although I've since found an even shorter solution: mov ax, 0x4681 lea ecx, [ecx+ecx*2] shr eax, cl and eax, 7 12 bytes.
