Product announcement, but hopefully it being open source silicon is interesting enough.
It’s a significant project in terms of scope. All the RTL, verification, firmware, and tests are on GitHub. There’s plenty of interesting stuff about the hardware design and security model in the documentation.
It’s a root of trust, you can think of it as a 32-bit RISC-V microcontroller with peripherals, cryptography accelerators, and a bunch of mitigations against fault injection and side channel attacks.
(I work on OpenTitan but not at Google, and not on the product)
