Parity generators and checkers are logic circuits used to implement parity checking schemes in digital systems. Parity checking is a method for detecting errors in transmitted data by adding an extra parity bit to the data stream. Parity generators calculate the parity bit based on the data inputs, while parity checkers verify the correctness of the received data by comparing it to the expected parity value. Parity generators and checkers are essential components in error detection and correction mechanisms employed in communication protocols, storage systems, and memory interfaces to ensure data integrity.
