ÐIterative division algorithms based on multiplication are popular because they are fast and may utilize an already existing hardware multiplier. Two popular methods based on multiplication are Newton-Raphson and Goldschmidt's algorithm. To achieve concurrent error correction, Time Shared Triple Modular Redundancy (TSTMR) may be applied to both kinds of dividers. The hardware multiplier is divided into thirds, and the rest of the divider logic replicated around each part, to provide three… CONTINUE READING
