An improved 32-bit Carry-Lookahead Adder with Conditional Carry-Selection

摘要：

An improved 32-bit carry-lookahead adder (CLA) with Conditional Carry-Selection (CSS) is proposed in this paper. The new adder is compared with Serial Adder and pure Carry- Lookahead Adder. The three adders is simulated in FPGA circuits, the results show that the propagation time of the carry of the new 32-bit adder is reduced 26％ compared with Serial Adder and 3.17％ with pure Carry-Lookahead Adder.

关键词： CSS CLA adder
