Multiplication Using Logarithms Implemented with Read-Only Memory
August 1975 (vol. 24 no. 8)
pp. 761-765
T.A. Brubaker, Department of Electrical Engineering, Colorado State University
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.
Index Terms:
Antilogarithms, logarithms, multiplication, read-only memory.
