Can anyone explain how the dual ARM/RISC-V system works, architecturally?
Are there two actual CPUs on the same die? Is it one shared architecture with two different instruction decode stages, one for ARM and the other for RISC-V that can be toggled at boot time? I like the idea conceptually but I'm not sure how much of that is a hack and/or inefficient compared to a pure ARM or RISC-V core.
