Arithmetic functions in programmable logic

As engineers begin to embed complex system functions within programmable logic, the need often arises to perform arithmetic functions. Altera's FLEX 8000 family addresses this need with the features of the Arithmetic LE Mode. In this mode, dedicated logic and routing generates and propagates a fast carry-forward function in less than 1 ns. This high speed carry generation can be used to build arithmetic functions that will meet the most demanding system requirements.<
