Abstract :Compensating the error using additional circuitry is mandatory in a low-error fixed-width multiplier. Instead of compensating the error, reconfiguring n-bit fixed-width multiplier to n/2-bit error-free full-width multiplier using decomposed multiplication is proposed in this paper. The decomposed block multiplication using an area-efficient New Bit Pair Recoding insert ignore into journalissuearticles values(NBPR); algorithm in fixed-width mode shows a relatively lesser truncation error than existing truncated multipliers. Reconfigurable 16x16   NBPR multiplier in three different modes insert ignore into journalissuearticles values(8x8, 16x8,16x16); with a fixed 16-bit product is verified on the TSMC 65nm CMOS standard cell library. The experimental results show that the NBPR multiplier consumes a lesser area than standard Booth multipliers. Evaluating the proposed multiplier in imaging shows improved PSNR with minimal error compared to other fixed-width multipliers
