First Post! Uh, I mean, First CHERIoT Silicon!

We have our first chips back! It is very exciting! Spatial and temporal memory safety, fine-grained compartmentalisation, and also a load of other big chips on a board, so you can play 'Where's ICENI?' on the board picture!

First CHERIoT Silicon!

Welcome to the CHERIoT Platform, a hardware-software co-design project that provides game-changing security for embedded devices.

@david_chisnall So https://cheriot.org/images/2026-03-04%20iceni.png is… a complete motherboard? Is there something I can look at to understand what all the stuff on the board is, just at a high level?

@amenonsen It's an embedded development board. The chip is a microcontroller (although, at 250 MHz, faster than many computers I've owned, and with more RAM than the first few).

It's got a few peripherals on the board, including Ethernet. We have a little SPI LCD that fits on top (but goes over the ICENI chip, so isn't on the board).

We have a limited run of these, we'll have more later in the year.

I'm honestly surprised that this one works at all. Our first chip actually running instructions, apparently correctly, is a testament to how awesome or DV team is.
