Approximate circuits and approximate circuit design methodologies attracted
a significant attention of researchers as well as industry in recent years. In
order to accelerate the approximate circuit and system design process and to
support a fair benchmarking of circuit approximation methods, we propose
a library of approximate adders and multipliers called EvoApprox8b. This library
contains 430 nondominated 8-bit approximate adders created from 13 conventional
adders and 471 non-dominated 8-bit approximate multipliers created from 6
conventional multipliers. These implementations were evolved by a multi-objective
Cartesian genetic programming. The EvoApprox8b library provides Verilog, Matlab
and C models of all approximate circuits. In addition to standard circuit
parameters, the error is given for seven different error metrics. The EvoApprox8b
library is available at: www.fit.vutbr.cz/research/groups/ehw/approxlib
