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!

@david_chisnall congrats on the fab

@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?

@david_chisnall First POST maybe? Congrats! Have fun with bringup.

@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.

When I first saw a 100 MHz Pentium, I thought it was the end of upgrade cycles. What could you possibly do with a 100 MHz CPU in your computer? And now our first microcontroller is 250 MHz. It also has more RAM than my first PC (Amstrad PC1640). Computers are so fast now!

@david_chisnall And yet desktop software can still feel slow, and griping about bloat and slowness is a perennial pastime among computer power-users and developers. Any idea what we can do to break the cycle of "what Andy giveth, Bill taketh away"?

@david_chisnall my first computer had all of 1kb of ram. The web browser I'm typing this on is currently using up 869376 ZX81s of memory!
