15.6 CONCLUSIONS
Similar to the strength reduction at algorithm level, numerical strength reduction can reduce the hardware complexity significantly. This chapter has addressed various numerical strength reduction approaches based on subexpression elimination or substructure sharing. These approaches can be exploited to reduce the implementation complexity of fixed-coefficient digital filters such as FIR and HR digital filters, multirate filters, and wavelet filters. It may be noted that subexpression elimination techniques are commonly used in compiler [7].
