This paper presents comparative analysis between two devices for the design of a radix 4 wallace tree multiplier that performs interval multiplication. This 64 bit multiplier requires Booth partial product selection logic and (27,2) compressor. This interval arithmetic gives accurate result as rounding off error of floating point multiplier is eliminated . It requires slightly more area than conventional floating point unit. There is definite performance improvement over software approach as function calls , error and range checking etc are not present due to dedicated hardware
