A method for designing the read-only memories (ROM's) needed for multiplication using logarithms is developed. By defining the word length of the multiplicand, multiplier, and product as n bits and the word length of -the rounded logarithms as m bits, design curves are given that allow various values of n and m to be selected for a given multiplier accuracy. Then a table is used to determine, which combination results in an implementation with the least number of bits.
