Overall Algorithm, Implementation, and Timing
The overall algorithm is shown in Figure 6.3 and its implementation at the block-
diagram level in Figure 6.4. The cycle time is
Tcycle =
tSEL + tF-CEX + tADD + tload

Examples of Implementations
We now describe two example implementations, one radix-2 and one radix-4.
The corresponding selection functions are derived in Section
6.6.
