Abstract

Due to the widespread implementation of UART (Universal Asynchronous Receiver-Transmitter), the data transmission speed has become a significant challenge, especially in applications requiring high performance. Improving the speed of UART communication is crucial to meet the growing demands of modern systems. This paper explores two main approaches to increasing the speed: protocol optimization and hardware implementation. The first approach, protocol optimization, involves examining and adopting advanced protocols to enhance efficiency. For instance, the 9-bit UART protocol can handle more data per frame, and the UVM (Universal Verification Methodology) environment protocol ensures robust communication with reduced overhead. These protocols aim to streamline data exchange and minimize latency. The second approach focuses on hardware implementation to boost performance. Techniques like utilizing DMA (Direct Memory Access) reduce CPU intervention during data transfer, while FSM (Finite State Machine) allows for efficient state-based control, improving overall processing speed. By combining these two approaches, it is possible to significantly enhance UART communication speed, making it suitable for high-speed applications.
