There are companies that specialize in FPGA to ASIC conversion, and I think it works by sharing masks with other custom ASIC orders. So I think it’s feasible at thousands of units. It’s something like 50% lower power and cost per unit than FPGA and a little higher speed as well. Not super dramatic, but is a pretty easy path. I think $10,000 to $35,000 non-recurring costs plus the cost of the chips themselves. Potentially in the Kickstarter range. Full custom ASICs get much higher performance, lower power, lower per unit cost but have like a minimum of $500,000 NRE costs.
