Real-time performance

Definition

Real-time performance refers to the ability of a system to process data and deliver results or actions almost instantaneously, with minimal delay. This is crucial in applications that require immediate responses, such as brain-machine interfaces (BMIs) where the timing of signal processing is essential for effective control and interaction. Achieving real-time performance involves optimizing algorithms and hardware to ensure that they can handle incoming data streams promptly while maintaining accuracy and reliability.
