Description

This IP core provides resource efficient ternary adders, i.e., adders with three inputs performing s = x + y + z, for the Altera and Xilinx platforms.
Resource efficient means that they need exactly the same resources on modern FPGAs as two-input adders, but are slightly slower.

A complete description can be found in the ternary adder documentation: http://opencores.orgusercontent,doc,1365162582

Note that the used method for the Xilinx ternary is patented (US patent no 7,274,211). Hence, only private, research or non-commercial use is allowed with this implementation!
