  For control unit: 0000 -nothing; 1000 - OR; 0100 - !(B->A); 1100 - AND; 0010 - EOR; 1010 - XOR; 0110 - A->B; 1110 - if A!=0; 0001 - NAND; 1001 - NOR; 0101 - if A==B; 1101 - if A!=B; 0011 - Summ; Maybe something wrong, but it's all that I remember.

  Try other formulas, they also have an interesting effect: !X XOR (X-1); !X AND (X-1); !(X-1) OR X; X XOR (X-1); X AND (X-1)

  !X OR (X-1) will set 0 last non zero bit and set 1 all other.

  Do You Know: !(X-1) AND X will allocate last non zero bit?
