A hardwired algorithm for computing the variable precision multiplication is presented in this paper. The computation method is based on the use of a parallel multiplier of size m to compute the multiplication of two numbers of nxm bits. These numbers are represented in the variable precision floating point format, but in this paper only the mantissas are considered; the exponents are easily obtained...
The execution performances of the Sweeney, Robertson, Tocher (SRT) division algorithm depend on two parameters: the radix-r and the redundancy factor p. In this paper, a study of the effect of these parameters on the division performances is presented. At each iteration, the SRT algorithm performs a multiplication by the quotient digit qi+1. This last can be just a simple shift, if the digit qii...
