Abstract:
1. An electronic device comprising: an integrated circuit (IC) comprising: a plurality of configuration data storage elements for storing configuration data; a plurality of configurable logic circuits for configurably performing a plurality of logic operations based on said configuration data; and a set of configurable routing circuits for configurably routing signals between the plurality of configurable logic circuits, each of the plurality of configurable logic circuits comprising first and second configurable look-up tables (LUTs), each configurable logic circuit's first LUT for (i) performing an arithmetic operation comprising at least one of an addition operation and a subtraction operation when receiving a first set of configuration data and (ii) performing a non-arithmetic operation when receiving a second set of configuration data, each configurable logic circuit's second LUT for receiving two logical bits of the first set of configuration data as entries of the second LUT in order to produce a propagate signal for the arithmetic operation performed by the first LUT.
