ABSTRACT:
Methods and apparatus are disclosed to implement programmable logic generators that provide the advantages of compatible look-up tables (LUTs) while utilizing less silicon real estate and power for the same number of functions. The disclosed methods and apparatus employ programmable switches to emulate memory units that are used in LUTs and illustrate construction of 2- and 3-input LUTs as building blocks of other multi-input LUTs.
