I speculate that this is all an outgrowth of the Mira video handling.

That's unlikely to be integrated to an ASIC.

I'm not against an FPGA. I have retail products with FPGA in them, but it's because they are niche (low production volume) and power consumption isn't an issue. Also one is costing about €1300, weighs about 6 kg, takes about 2.5 A @ c.14V when idle and is very much more complex than a PC or eReader, so the fact it uses a massive spec FPGA rather than an ASIC is irrelevant.

It also wouldn't be odd in a high end PCIe graphic card for a niche market. That might take 100x the power of an ereader.

The FPGA suggests that either Onyx is very short of cash or isn't confident about the sales volume, or isn't confident about bugs in the design (you can upgrade the design file for an FPGA the user has, but updating an ASIC means a new set of masks and massive NRE charges and only affects future production, it's a new chip).
