Example 2: 3-Bit Adder Using a Carry Chain
FLEX 6000 devices have specialized resources that implement complex
arithmetic functions. For instance, adders and counters require a carry
function to determine whether or not to increment the next significant bit.
The FLEX 6000 architecture has a built-in carry chain that performs this
function. This example explains how to estimate the delay for a 3-bit
adder that uses a carry chain (see
Figure 6
).
