4.7. [Optional] Using Symmetric Multi-Processing to deliver higher performance

You can use SMP to deliver higher performance if performance is a concern. ARMv7-A introduces support for SMP, which allows multiple identical processing subsystems on a single chip, all running the same instruction set and with equal access to memory, I/Os, and external interrupts.

By using multiple cores, the CPUs of today can complete more work faster, and at lower power, than their single core predecessors. SMP enables mobile processors to not only deliver higher performance, but also meet peak performance demands while staying within mobile power budgets.
