Term: UART
Definition: A widely used protocol for serial communication that allows for data transmission without a clock signal.
Term: AXI4Lite
Definition: A protocol used for control register access in AXI interfaces, facilitating efficient configuration of peripheral parameters.
Term: FIFO
Definition: First-In-First-Out buffer used in AXI UART and AXI4-Stream for temporary data storage during transmission.
Term: Flow Control
Definition: Mechanisms like RTS and CTS in UART that manage the flow of data between sender and receiver to prevent data loss.
Term: Handshake Signals
Definition: Signals used in AXI4-Stream to ensure data synchronization between master and slave components during data transfer.
