10. Programming an SoC Using C Language

Programming an SoC with C requires a comprehensive knowledge of the hardware components, memory management, and peripheral interaction. An SoC merges various parts of a computer into a single chip, offering efficiencies for embedded systems programming. C is favored for its efficiency and low-level control over hardware, allowing developers to optimize performance and manage resources effectively.
