Interesting to see, hope they make progress on preventing the spectre attacks, since these are still relevant today. See this paper that was presented at the WHY2025 hacker camp: https://openreview.net/pdf?id=4tDNvQe2G0
Speculative execution > Variants,: https://en.wikipedia.org/wiki/Speculative_execution
Transient execution CPU vulnerability: https://en.wikipedia.org/wiki/Transient_execution_CPU_vulner...
Does RISC-V have speculative execution?
A RISC-V CPU out of graphene would be more efficient.
openhwgroup has open Verilog implementations of RISC-V cores from 2 stages through 6 stages that will boot Linux: https://github.com/openhwgroup
There are various optional feature flags for RISC-V.
The RISC-V open ISA is probably advantageous especially for research implementations.
