The Kindle doesn't come with a lot of onboard horsepower, and putting the same class of SoC as a Raspberry Pi in one would likely increase cost and have other tradeoffs.
- tadfisher 5y agoI'm assuming the Kindle is using an i.MX6 or better NXP SOC, because they are basically the only ones shipping an integrated EPD controller with Linux drivers, which should be more than capable of parsing and rendering HTML. The Remarkable series runs Qt on these chips and is able to render ePub documents just fine.
