Abstract

See full text

Some embodiments of the invention provide a configurable integrated circuit (“IC”). The configurable IC includes a set of configurable logic circuits for configurably performing a set of functions on a set of inputs. The IC also includes several input select interconnect circuits for selecting the input set supplied to each configurable logic circuit. Each input select interconnect circuit is associated with a particular configurable logic circuit. When a configurable logic circuit is used to perform a multiplication operation, at least one of its associated input select interconnect circuits performs a logic operation that implements part of the multiplication operation.
