Implementation and Comparative Analysis between Devices for Double Precision Interval Arithmetic Radix 4 Wallace tree Multiplication

摘要

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
