combinations of valid partitions and the encoding schemes applied to the parti-

tions. Then, a confi guration is selected that on average results in maximum self

and coupling energy reduction. The PHE scheme was shown to provide 4 to 13

times more savings than the BI and OEBI schemes for the SPEC2000 benchmarks.

An approach to reduce leakage (due to buffers inserted on bus lines) and

crosstalk power, by using simultaneous buffer design and encoding was proposed

by Deogun et al. [84] and Rao et al. [85]. A staggered threshold voltage (STV) buf-

fer was proposed, constructed by combining low threshold ...
