Looking back at the continuously evolving smartphone market, it is amazing to note the role that the ARM Cortex-A7 core has played. Previously the processor which initiated the uptake of multicore processing in mobile, the ARM Cortex-A7 is now an increasingly popular choice in energy-efficient mobile computing, enabling devices to achieve high-end functionality alongside all-day battery life and a very competitive price point. Devices based on the mature Cortex-A7 can now be typically found for well under $200, and this is driving widespread uptake in emerging markets such as Brazil and India. (Figure 1: ARM Cortex-A7 processor design) On top of its extreme energy efficiency, the Cortex-A7 incorporates many features of the high-performance Cortex-A15 and Cortex-A17 processors, including virtualization support in hardware, Large Physical Address Extensions (LPAE), NEON®, and 128-bit AMBA® 4 AXI bus interface. It provides up to 20% more single thread performance ...
