Abstract
Integrated circuits with programmable logic regions are provided. The programmable logic regions may be organized into smaller logic units sometimes referred to as a logic cell. A logic cell may include four 4-input lookup tables (LUTs) coupled to an adder carry chain. Each of the four 4-input LUTs may include two 3-input LUTs and a selector multiplexer. The carry chain may include at three or more full adder circuits. The outputs of the 3-input LUTs may be directly connected to inputs of the full adder circuits in the carry chain. By providing at least the same or more number of full adder circuits as the total number of 4-input LUTs in the logic cell, the arithmetic density of the logic is enhanced.
