Approximate circuits are building blocks of complex systems on a chip that can
exchange the quality of processing for power consumption reduction. The design of
an approximate circuit showing good tradeoffs between the error and other
parameters is still a challenging task. We propose to reduce the design time and
increase the complexity of circuits that can routinely be approximated by (i)
developing a comprehensive library of elementary approximate circuits and (ii)
introducing suitable compositional schemes exploiting the elementary circuits
available in the library. Assembling a complex approximate circuit from
approximate sub-circuits is a challenging problem as it is, in general, unclear
how to perform the (de)composition and how the errors of these sub-circuits
manifest at the global level. The project seeks the following contributions: (1)
efficient deterministic and evolutionary compositional algorithms for approximate
circuit design, (2) a library containing over 1 million approximate circuits, and
(3) new knowledge about approximate circuits by analyzing the library.
