Hardware implementation

Definition

Hardware implementation refers to the process of designing and constructing physical devices or circuits that execute specific functions, especially in the realm of coding theory and error correction. This involves creating hardware components that can perform tasks such as encoding, decoding, and interleaving data to enhance performance and reliability in communication systems. Effective hardware implementation can significantly improve processing speeds and resource efficiency, allowing for real-time data handling in various applications.
