Abstract
An electronic device ( ) includes squaring circuit ( ) that includes a logarithmic compression function ( ), a squaring function ( ), a doubling function ( ), and a logarithmic decompression function ( ). The logarithmic compression function ( ) accepts a binary input ( ) of width W and value X, and produces an output having a binary power component ( ) and a binary magnitude component ( ). The squaring function ( ) generates an adjusted squared magnitude component ( ) and a selection signal ( ). The doubling function ( ) generates a doubled power component ( ). The logarithmic decompression function ( ) generates an approximate squared output ( ) of width 2W from the doubled power and adjusted squared magnitude components ( ). The approximate squared output ( ) has a value that approximates the square of X to a predetermined amount of precision, N.
