ABSTRACT:
A floating-point division cell consisting of partial remainder data register for storing parallel-partial-remainder data or third partial remainder data, divisor data register for storing parallel-divisor data or third divisor data, low-order divisor data generator for receiving the low-order portion of the divisor data and generating low-order divisor data, low-order partial remainder calculator for obtaining low-order multi-divisor data by multiplying the low-order divisor data and a multiple of 2 together and calculating new low-order partial remainder data by subtracting or adding the low-order multi-divisor data from/to the low-order portion of the partial remainder data, high-order divisor data generator for receiving the high-order portion of the divisor data and generating high-order divisor data, and high-order partial remainder calculator for obtaining high-order multi-divisor data by multiplying the high-order divisor data and a multiple of 2 together and calculating new high-order partial remainder data by subtracting or adding the high-order multi-divisor data from/to the high-order portion of the partial remainder data.
