Application Processor

The application processor is the technical term given to a processor of an iDevice. There have been many incarnations of processors for Apple's mobile devices.

Features
Each revision is an ARM SoC tailored to the device's needs. All of Apple's SoC platforms have proprietary PowerVR graphics, public key encryption accelerators, hardware crypto and so on. The cores are mainly generic ARM ones, however, in the case of Swift, Apple used their own core design, compatible with ARMv7-A architecture and VFPv4 floating point.
