Arithmetic Circuits » IQ – 1
1. The two basic ways to transfer digital information are parallel – all bits simultaneously and serial – one bit at a time.
2. The arithmetic/logic unit (ALU) of a computer contains the circuitry needed to perform arithmetic and logic operations on binary numbers stored in memory.
3. The accumulator is a register in the ALU. It holds one of the numbers being operated upon, and it also is where the result of the operation is stored in the ALU.
4. A full adder performs the addition on two bits plus a carry input. A parallel binary adder is made up of cascaded full adders.
5. The problem of excessive delays caused by carry propagation can be reduced by a look-ahead carry logic circuit.
6. IC adders such as the 74LS83/HC83 and the 74LS283/HC283 can be used to construct high-speed parallel adders and subtractors.
7. A BCD adder circuit requires special correction circuitry.
8. Integrated-circuit ALUs are available that can be commanded to perform a wide range of arithmetic and logic operations on two input numbers.
