Event-driven processing

Definition

Event-driven processing is a computational paradigm that reacts to changes in the system's environment by triggering actions based on specific events. This approach allows for efficient handling of asynchronous events and is particularly valuable in contexts where data is generated sporadically, such as with sensory input or real-time systems.

Review Questions

• How does event-driven processing enhance the performance of neuromorphic sensors and actuators?
  • Event-driven processing enhances neuromorphic sensors and actuators by enabling them to respond dynamically to changes in their environment. This means they can act only when significant events occur, leading to faster reaction times and reduced power consumption. By mimicking the way biological systems process stimuli, these sensors can efficiently handle sensory data and provide timely responses in various applications.
• Discuss the role of event-driven processing in achieving energy-efficient computing within neuromorphic systems.
  • Event-driven processing plays a crucial role in achieving energy-efficient computing by ensuring that computations occur only when necessary. This reduces the overall power usage since the system avoids constant data processing and instead focuses on relevant events. As a result, neuromorphic systems can operate effectively while conserving energy, which is particularly important for mobile and embedded applications.
