  • Patent number: 6751645
    Abstract: An SRT division unit for performing a novel SRT division algorithm is presented. The novel SRT division algorithm comprises a method for performing SRT division using a radix r. As one skilled in the art will appreciate, the radix r dictates the number of quotient-bits k generated during a single iteration. The relationship between radix r and the number of quotient-bits k generated in a single iteration is r=2k. The number of iterations needed to determine all quotient-digits is N, such that N=54/k for a 64 bit floating point value. In accordance with one embodiment of the present invention, the SRT division unit generates a scaling factor M, which comprises scaling sub-factors M1 and M2 according to the relationship M=r*M1+M2. Next, the division unit generates a scaled divisor Y by multiplying a divisor DR by scaling factor M, such that said scaled divisor Y=DR*M=r(DR*M1)+DR*M2.
