The ARM architecture is divided into 7 branches, not 3.
🔵Cortex-A: Application Processor, aimed at application processors.
🔵Cortex-M: Microcontroller, aimed at microcontrollers.
🔵Cortex-R: Real-time Processor, aimed at real-time processing.
🔷Cortex-X: Ultra-high-performance processor.
🔷Neoverse V Series: High-performance computing (HPC) and cloud computing. Application scenarios: high-performance computing, machine learning, big data analysis, etc.
🔷Neoverse N Series: General cloud and edge computing. Application scenarios: cloud services, content delivery networks, edge computing, etc.
🔷Neoverse E Series: Energy-efficient optimization for edge and embedded applications. Application scenarios: networking devices, IoT, entry-level servers.
