Lookup tables for A-law and u-law look attractive, until you consider the impact
on the CPU cache. If it causes a substantial area of your processor cache to get
hit too often, cache sloshing will severely slow things down. The main reason
these routines are slow in C, is the lack of direct access to the CPU's "find
the first 1" instruction. A little in-line assembler fixes that, and the
conversion routines can be faster than lookup tables, in most real world usage.
A "find the first 1" instruction is available on most modern CPUs, and is a
much underused feature.
