The arithmetic logic unit handles arithmetic operations in the CPU.
Operators
The main operators include
- ADD
- SUB: A - B = A + (-B)
- MUL2: 2*A = A + A
- XOR
- NOT: ~A = A XOR 1
- AND
- OR
Circuit
Arrangement of instruction opcodes may ease circuit construction. By experience, arithmetic and logic instructions should be separated.
