I thought the reason it was generally accepted that the 8-bit lookup table is optimal is because it can fit in the L1 cache.

  (Very) embedded developer speaking here. What's this L1 cache you speak of?

    It's level 1 CPU cache, the fastest (and smallest) cache. It caches both instructions and data. https://en.wikipedia.org/wiki/CPU_cache https://en.wikipedia.org/wiki/CPU_cache

      GP is making the point that not all CPUs have a cache.

      It was a joke. Some embedded processors lack a cache.
