Why A9 is multicore by A8 doesn't

Hi Experts,

Which factor in processor decides whether it can be used in multi-core or not ?

Like as per my understanding A8 is used in single core whereas A9 is used in multi core. So which distinctive feature in A9 favors the multi core application ?

Hi techguyz,

I would give a simple answer. Regarding multi-processor, the features which A9 has and A8 does not have are SCU (Snoop Control Unit), the distributed interrupt controller and ACP (Accelerator Coherency Port).
