Speculative Carry Generation With Prefix Adder
Youngmoon Choi, Earl E. Swartzlander · IEEE Transactions on Very Large Scale Integration (VLSI) Systems · 2008
A framework that generates formal prefix equations for speculative carry generation is presented. It is applicable to both normal carry and Ling carry adders and generates four forms of speculative carry generate prefix schemes (two forms for each carry case). For normal carry, one corresponds to an existing design and the other is newly introduced. For the Ling carry, both are newly proposed.
