If you are on ARM and already using Keil: . Keil’s compiler is also excellent. VX shines when you need ISO 26262 documentation. Otherwise, the ARM VX port is a niche within a niche. Final Verdict The TASKING VX-toolset is the professional embedded engineer’s scalpel. It is precise, dangerous if mishandled, and utterly irreplaceable for certain tasks. The learning curve is steep (LSL alone will cost you a weekend), but the payoff is deterministic, safe, and fast code. // Atomic compare and swap __cmpswap(ptr, old_val, new_val);
