The claims of the patent in question do not specify the use of a lookup table.
Also - this was a high stakes patent litigation where the defendant (Apple) has literally unlimited funds available to try an invalidate the asserted patent. They have some of the best patent lawyers around and access to the best patent litigators in the world. And they still lost. Given that context, your assertion that no previous art exists is questionable at best.
The patent is also from 1998. Given many years of hindsight and compounding knowledge, old patents can seem obvious now when they weren't at the time. If both Intel and Apple couldn't invalidate the patent then I think I will be OK without the armchair-CPU-architects giving their armchair-patent-lawyer-analyses of the situation.
