Globally asynchronous locally synchronous

Definition

Globally asynchronous locally synchronous refers to a design approach in systems where different components operate asynchronously with respect to a global clock but maintain synchronous behavior locally within their own sub-units. This method allows for improved performance and flexibility, particularly in complex systems like neuromorphic circuits, where parts can function independently while still being able to communicate and work together effectively.

5 Must Know Facts For Your Next Test

1. In globally asynchronous locally synchronous systems, local synchronization allows components to optimize their operation while still supporting global communication.
2. This design approach helps reduce power consumption by allowing parts of the system to sleep or operate at different speeds based on demand.
3. Globally asynchronous locally synchronous architectures can enhance fault tolerance, as individual components can continue functioning even if others experience issues.
4. The approach is especially beneficial in neuromorphic engineering, where mimicking biological neural networks often requires asynchronous interactions between neurons.
5. Implementing this method can lead to more efficient designs, as it allows for parallel processing capabilities without the overhead of a global clock.
