Solution
The primary difference between restoring and non-restoring algorithms in division lies in their operations and efficiency.
-
Restoring Algorithm: This algorithm uses the traditional method of division. It involves a series of subtractions and comparisons. If the remainder becomes negative, the last subtracted divisor is added back, making the remainder positive. This is why it's called the "restoring" algorithm.
-
Non-Restoring Algorithm: This algorithm is more efficient than the restoring algorithm. It uses two's complement arithmetic and requires fewer iterations. If the remainder becomes negative, it does not restore the last subtracted divisor. Instead, it proceeds with the next step using the negative remainder, hence the name "non-restoring".
In summary, the restoring algorithm ensures the remainder is always positive by adding back the last subtracted divisor if necessary, while the non-restoring algorithm does not. The non-restoring algorithm is more efficient as it requires fewer iterations and uses two's complement arithmetic.
