Abstract :
The mathematical basis for developing an unsigned SRT table for division, multiplication-division or square-root operations is summarised. This is possible through utilising the P-D diagram symmetry allowing a 50% reduction in table size. Efficient implementation that avoids a serious problem with the implementation suggested by Kornerup in 2003 is demonstrated and conditions for its error-free operation are discussed.
