Cortex-A Application Processors deliver exceptional performance of up to 2GHz+ typical frequency in advanced process nodes, enabling the next generation of mobile internet devices. The processors are available in single-core and multi-core varieties, delivering up to four processing units with optional NEON multimedia processing blocks and advanced Floating Point execution units.

Cortex-R series processors however have been developed for deeply embedded real-time applications where the need for low power and good interrupt behaviour are balanced with exceptional performance and strong compatibility with existing platforms.

Cortex-M series processors have been developed primarily for the microcontroller domain where the need for fast, highly deterministic, interrupt management is coupled with the desire for extremely low gate count and lowest possible power consumption.

ARM Cortex-R real-time processors offer high-performance computing solutions for deeply embedded systems with demanding real-time response constraints. Target applications are: Mobile handset processing in smart-phones and baseband modems, Enterprise systems such as hard disk drives, networking and printing, Home consumer electronics, set top boxes, digital TV, media players, cameras
Embedded microcontrollers for dependable systems in medical, industrial and automotive.

Within these applications are systems that set hard deadlines on processing response. To avoid data loss or mechanical damage, meeting these deadlines is crucial. The design of Cortex-R processors specifically addresses the need for high performance, dependability and error-resistance with highly deterministic behavior while maintaining energy and cost efficiency.

Cortex-A50 series processors are excellent dual 32-bit and 64-bit processors. They deliver more performance for ARMv7 32-bit code in AArch32 execution state, and offer support for 64-bit data and larger virtual addressing space in AArch64 execution state

The ARMv8-A architecture allows clean interworking between 32-bit and 64-bit in AArch64 state, enabling a step-by step migration to 64-bit, beginning with 64-bit operating systems running 32-bit ARMv7 applications, migrating to a mix of 32-bit applications and 64-bit applications running in the same system.

With the ARMv8-A architecture, the Cortex-A50 series processors also introduce more advanced SIMD capability, instructions to speed up software cryptography, increased register files, flexible addressing modes, support for tagged pointers, 64k data pages, a new exception model, enhanced cache management and enhanced floating point operations (IEEE754-2008).
