Description: Bus coupling refers to the connection of multiple buses to allow communication between them. In the context of digital systems, this concept is fundamental for the interconnection of different modules and components. Buses are data pathways that transport information between different parts of a circuit, and bus coupling enables these pathways to integrate efficiently. This approach facilitates data transfer, optimizes resource usage, and enhances design modularity. The main characteristics of bus coupling include the ability to handle multiple signals simultaneously, flexibility in bus configuration, and the possibility of scaling the system by adding more components. Additionally, bus coupling is essential for data synchronization, as it allows different parts of the system to operate in a coordinated manner. In summary, bus coupling is a key technique in the design of digital systems, especially in applications that require high interconnectivity and efficiency in communication between components.
