Runtime soft error detection techniques in hardware, such as error signaling and error correcting circuits, play a crucial role in identifying and mitigating errors. Relying on a not robust technique may result in unstable application and bad user experience. Here is a quick overview of some of most used one –
Parity Check:
Benefits:
Parity check is a simple and efficient technique to detect single-bit errors. It has low hardware overhead and is easy to implement.
Drawbacks:
