Design of low-error fixed-width multiplier for DSP applications

A low-error design of the fixed-width parallel multiplier for digital signal processing (DSF) applications is proposed. Applying two n bit inputs, it generates the n bit, instead of 2n bit, product with lower relative product errors, but uses only about half the area of a standard parallel multiplier. These features make it very suitable for use in many DSP applications such as arithmetic coding, wavelet transformation, digital filtering
