In fact, even if you want to supply the geometry values from a table (so you're multiplying by variable values) that's no big deal; two multipliers won't make a dent in any modern FPGA.

That's why that's my first choice.  I just don't think it will be a problem.

The original reason for the microcontroller is to implement the USB
protocol.  I didn't feel up to that in Verilog.
