Latest Patents

Ranjan's latest patents include advancements in parallel-prefix adder technology. The first patent describes an adder that features a primary carry bit generation circuit and a summing circuit. This design allows for the generation of first carry bits for a specific number of pairs of bits from two operands, as well as second carry bits for a different number of pairs. The summing circuit is adept at generating sums by adding bits from these pairs along with the corresponding carry bits.

The second patent presents a parallel prefix adder structure that utilizes a carry bit generation circuit to produce primary carry bits for selected bit pairs. This structure incorporates ripple carry adders that leverage these primary carry bits to derive secondary carry bits and final sum bits. The design is characterized by different sections that process various sets of bit pairs, resulting in a non-uniform generation of primary carry bits, which optimizes performance based on the operand size.
