Abstract |
|
Low-cost finite impulse response (FIR) designs are presented using the concept of faithfully rounded truncated multipliers. Here the optimization of bit width and hardware resources without sacrificing the frequency response and output signal precision are considered. In this multiple constant multiplication/accumulation (MCMA) is used to reduce the area, which reduces the cost and power dissipation and hardware resources also reduced. The MCMA module is realized by accumulating all the partial products (PPs) where unnecessary PP bits (PPBs) are removed without affecting the final precision of the outputs. The bit widths of all the filter coefficients are minimized using non uniform quantization with unequal word lengths in order to reduce the hardware cost while still satisfying the specification of the frequency response. |
