Cortex

The ARM Cortex family comprises three series, which all implement the Thumb-2 instruction set to address the increasing performance and cost demands of various markets:


 * ARM Cortex-A Series, applications processors for complex OS and user applications.Supports the ARM, Thumb and Thumb-2 instruction sets
 * ARM Cortex-R Series, embedded processors for real-time systems. Supports the ARM, Thumb, and Thumb-2 instruction sets
 * ARM Cortex-M Series, deeply embedded processors optimized for cost sensitive applications. Supports the Thumb-2 instruction set only
