What is the benefit of using multiple bus architecture compared to a single bus architecture ?

Following are the benefits of using multiple bus architecture compared to
single bus architecture :

1. Faster Data Transfer: Imagine a single bus as a single lane road where only one car (or data item) can pass at a time. This can lead to traffic jams (long control sequence) if there’s a lot of data to transfer. With multiple bus architecture, it’s like having multiple lanes, allowing several cars (data items) to move simultaneously, speeding up the transfer process.
2. Reduced Steps: Think of each step in processing as a checkpoint that data needs to pass through. In a single bus setup, each piece of data has to go through every checkpoint one after the other. But with multiple buses, we can have different paths for data to take, reducing the number of checkpoints it needs to pass through, making the journey quicker.
3. Efficient Use of Resources: Instead of adding more load to a single processing unit (ALU) to handle additional tasks like incrementing, in multiple bus architectures, we can have dedicated units (like an incrementer unit) to handle specific tasks, making the overall process more efficient.
4. Quicker Execution: Picture a conveyor belt in a factory. If there’s only one belt, each item has to wait its turn to move forward. But if there are multiple belts, several items can move simultaneously, speeding up the process. Similarly, with more paths for data transfer (multiple buses), instructions can be executed faster because data can travel through different routes simultaneously, reducing the time it takes to complete tasks.
