The ARM Cortex-R is a family of processors designed for real-time applications that require high reliability and performance. These processors are commonly used in systems such as automotive control, industrial automation, and telecommunications. They support features like error correction and fault tolerance, making them suitable for critical tasks. Cortex-R processors are built on the ARM architecture, which allows for efficient power consumption and processing capabilities. They are optimized for low-latency response times, ensuring that they can handle time-sensitive operations effectively. This makes them a popular choice for embedded systems that demand both speed and dependability.
