While the world moves to multicore, many embedded tasks in Japan were traditionally single-core. The shift to multicore brings issues of concurrency and timing interference. Hypervisors solve this, but Japanese engineers require extensive proof that partitioning works perfectly (via Timing Analysis Tools ).
