Modern digital systems, asynchronous FIFO, basic principles, development status, innovation directions
Abstract
As modern digital system scales expand, multi-clock domain designs are common. Asynchronous FIFO is crucial for cross-clock domain data transmission. This paper studies its design and implementation. Firstly, it explains the importance and purpose, like solving data transmission issues and enhancing system stability. Then, it details basic principles including working principles and solutions for asynchronous clock interaction. For design status, it analyzes common architectures and hardware implementation with optimization strategies. It also points out challenges like reliability and performance-resource balance. Looking ahead, it anticipates future trends towards higher performance, lower power consumption, and stronger adaptability. Innovation directions may include new architectures and algorithms. Research shows asynchronous FIFO is important but needs improvement to meet growing needs. As electronic systems become more complex, the requirements for data processing speed and efficiency are also increasing. This has led to a growing demand for asynchronous FIFO. As data rates increase, asynchronous FIFOs need to be designed to be more efficient
