Abstract

The embodiments of the present invention relate to the general area of the Field Programmable Gate Arrays, and, in particular to the architecture and the structure of the building blocks of the Field Programmable Gate Arrays. The proposed logic units, as separate units or cluster of units, which are mainly comprised of look-up tables, multiplexers, and a latch, implement functions such as addition, subtraction, multiplication, and can perform as shift registers, finite state machines, multiplexers, accumulators, counters, multi-level random logic, and look-up tables, among other functions. Having two outputs, the embodiments of the logic unit can operate in split-mode and perform two separate logic and/or arithmetic functions at the same time. Clusters of the proposed logic units, which utilize local interconnections instead of traditional routing channels, add to efficiency, speed, and reduce required real estate.
