D.M. Lewis (ibid., vol.39, no.11, p.1325-36, Nov. 1990) recently described an architecture for performing addition and subtraction in the logarithmic number system using a Taylor series approximation and ROM tables. Here it is shown that a 25% improvement can be achieved in the table used to implement addition. This improvement is significant when Lewis' technique is used to implement variations of the logarithmic number system which do not require the subtraction logarithm.<>
