[sdiy] Using 8051 to build a synth

I think you may have to use machine code to do the multiplication on the
8051 - although the Cygnal C8051F120 has a built-in multiply function:

You just write to some memory, perform two NOPs and then your result can be
obtained (three NOPs if you want the extra information first). It does
rounding and saturation too.

I've just ordered a development kit from Digikey - a smidge under £100 inc
VAT (although £12 postage on top of that) - this has most of the available
functionality (mainly what I want are the DAC outputs [although only 12
bit] - saves me doing any soldering work!)
