Low power linear digital signal processing circuits are fabricated based on a design synthesis process using activity metrics. The average activity value .theta..sub.i of all the input nodes of the circuit is determined. Architectural transformations of the circuit are performed in order to ...http://www.google.com.au/patents/US5808917?utm_source=gb-gplus-sharePatent US5808917 - Synthesis of low power linear digital signal processing circuits using activity metrics
