The Cortex-R, characterized by fast response, is a processor optimized for high-performance, real-time applications. It represents ARM's Cortex processor series, along with the Cortex-A, primarily used in smartphones, and the ultra-low-power, small-sized Cortex-M. ARM's recently announced Cortex-R8, a processor supporting 5G speeds, is planned for next-generation LTE Advanced Pro, 5G-based mobile baseband standards, and high-capacity storage applications.
