Description: GALS, which stands for Globally Asynchronous Locally Synchronous, is a design methodology used in digital circuits that combines the advantages of asynchronous and synchronous systems. In a GALS system, components can operate independently and asynchronously at a global level, while at a local level, within each module, synchronous techniques are employed. This duality allows for greater flexibility in circuit design, facilitating the integration of different technologies and optimizing performance. GALS systems are particularly useful in applications where high energy efficiency and precise timing control are required, as they allow modules to communicate without relying on a global clock, thus reducing energy consumption and improving scalability. Additionally, this methodology helps mitigate synchronization issues that can arise in larger and more complex systems, making it an attractive option for modern integrated circuit design. In summary, GALS represents an innovative approach in digital circuit architecture, offering a balance between flexibility and efficiency in design.
