15-minute session: read for 3 minutes, trace for 3, experiment for 7, and complete the check for 2. Spend longer whenever you need.
x86-64, AArch64, and RV64 use different instruction encodings and register conventions. AArch64 names 64-bit general registers X0–X30; RV64I has x0–x31 with x0 fixed to zero. The ABI adds calling conventions, stack rules, and binary interfaces. Compare a function call in the official manuals, then list which assumptions a compiler backend must change. A shared 64-bit label does not make binaries interchangeable.
Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.
