EvoApprox8b

library of approximate arithmetic circuits

This is a GitHub repository of EvoApprox8B library. The library consists of hardware and software models of unsigned approximate 8-bit adders (486 circuits) and multipliers (505 circuits) that are designed to be easily used in arbitrary application.

The library was replaced by new version.

The new version can be found on our websites
