Radix-based division is described. A dividend operand and a divisor operand are obtained. An estimate that is a reciprocal of the divisor operand is obtained. For a prescaling mode, a prescaling iteration is performed which includes: multiplying the divisor operand with the estimate to provide a prescaled divisor; apportioning the dividend operand into portions from most significant to least significant; providing the estimate to iteration blocks ordered from highest to lowest; providing the most significant to the least significant of the portions of the dividend operand respectively to the highest to the lowest of the iteration blocks; respectively multiplying the portions of the dividend operand with the estimate to provide first partial products; and parsing most significant residue portions and least significant residue portions as associated with order of the iteration blocks from the first partial products. |
