What is the central processing unit in a CPS node responsible for?

The central processing unit (CPU) in a CPS (Cyber-Physical System) node is primarily responsible for executing programs and processing data. This function is crucial because the CPU acts as the brain of the CPS, managing the operations that allow the system to perform tasks based on the software instructions it receives.

Within a CPS, the CPU interprets data from various sensors or inputs, executes the control algorithms, and sends commands to actuators to carry out specific functions. This role is essential for the overall functionality of a CPS, as it enables the system to respond dynamically to environmental changes and process information in real-time.

While executing software updates, controlling the power supply, and collecting environmental data are important components of a CPS, they are more specific functions and are often handled through other dedicated subsystems or components within the architecture. The processing and execution of instructions by the CPU underlie all of these activities, establishing it as the core element in managing the operations and making decisions based on data input.
