NVidia's Kal-El SoC implements this approach, although it uses Cortex A9 for both the Big Dog and Little Dog cores. The Little Dog is produced using low-leakage transistors, which is where their obtain their power savings (at the cost of clock speed). In the Kal-El design, the Little Dog communicates with the Big Dogs through a shared L2 cache.
