<p>You are probably going to have to have a master to set everything
up and multiple processors to output stuff in parallel.</p>
<p>Figure out which interface you are going to use. Probably SPI or
I2C, even though a lot of SPI interfaces run at 50 MHz it's going
to take PCB rocket science to get it to work that fast.<br>
<br>
Then pick your chips you're going to use.<br>
<br>
Last thing is do a calculation to figure out how long it actually
takes to do a transfer.</p>

<div>What is the current ideal way to generate a large number
of CV outputs from a single CPU?<br>
<br>
Let's say I wanted to generate 100 outputs with an update
rate of a few kHz and an equivalent bit depth of 12 or 16
bits.</div>

<div>I know that back in the day when DACs were extremely
expensive, the designs would use a single DAC and then demux
to a bunch of S&Hs. <br>
<br>
Now that DACs are cheaper, is it better to chain a bunch of
8- or 16-channel DACs? <br>
<br>
Or would it make more sense to use an FPGA and create a
giant multi-channel 1-Bit DAC?<br>
<br>
Looking at some Elektron hardware teardowns it appears that
they are using the latter approach.</div>
