I'm working right now on a system that mixes Aarch32 and Aarch64 cores. Communication between these cores has to be rock-solid.
Previously, I worked on a DSP architecture that could switch at runtime between a 16-bit more and a 24-bit mode. I still sometimes have nightmares. A particular bug that took months to resolve involved app code that expected one mode and interrupts that went into another. The compiler did the right thing most of the time. Most of the time.
