Comments, on "A signed bit-sequential multiplier" by T. Rhyne and N.R. Strader II

With reference to the above mentioned paper (see ibid., vol.C-35, p.896-901 (1986)), it is stated that the authors´ introduction, in which they claim that the references all deal with algorithms for processing unsigned operands, is erroneous. One of their references most certainly does not deal with unsigned operands, as a two´s complement number system is one of the module interfacing conventions germane to R. Lyon´s (1981) methodology. Moreover, in the authors´ conclusions they state that they ´have now extended bit-sequential multiplication to signed, two´s complement binary operands´, which may give the (doubtless unintended) impression that this has not been done before.<>
