A Radix-16 SRT Division Unit with Speculation of the Quotient Digits
The speed of a divider based on a digit-recurrence algorithm depends mainly on the latency of the quotient digit generation function. In this paper we present an analytical approach that extends the theory developed for standard SRT division and permits to implement division schemes where a simpler function speculates the quotient digit. This leads to division units with shorter cycle time and variable latency since a speculation error may be produced and a post-correction of the quotient may be necessary. We have applied our algorithm to the design of a radix-16 speculative divider for double precision floatingpoint numbers, that resulted to be faster than analogous implementations.
