We introduce a PN
selection algorithm (PNSA) which enables designers to select
power efficient dynamic modules for different applications,
based on the detailed analysis of dynamic circuits.
Experimental results on ISCAS85 and 74X-Series
benchmark circuits show that the power consumption of 8-bit
ALU based on this approach can be reduced by 54%-60% for
different frequency levels as compared to the conventional
dynamic ALU design, demonstrating the effectiveness of the
proposed method on application-driven custom ALU design.
