I've been clumsily exploring the space of what kind of DSP you can do without multipliers, because (in hardware) multiplication is one or two orders of magnitude more expensive than addition; see https://nbviewer.org/url/canonical.org/~kragen/sw/dev3/spars... for one example.

This is a fascinating space where logarithmic numbers can offer a lot of value with fewer bits.
