Method and apparatus for performing prescaled division

摘要

An arithmetic circuit 10 for performing prescaled division uses a rectangular multiplier 16 and accumulator 30 operable to calculate a short reciprocal and scaled dividend and divisor to enable the sequential iterative calculation of large radix quotient digits. Each quotient digit can be calculated using a single pass through the rectangular multiplier 16 and accumulator 30 and can be accumulated to form a full precision quotient in a quotient register 36.
