Patent abstract

A particular embodiment of the present invention provides a shared-LUT logic circuit that provides the functionality of two (n+1)LUT logic circuits without requiring approximately twice the resources of two nLUT circuits. In some embodiments, a shared-LUT logic circuit is provided that can be configured to operate in multiple modes including, for example, an nLUT mode, an (n+1)LUT mode, and other modes.
