Abstract
Systems, methods, and circuits utilize one or multiple data-stream watchdog codes for verifying a temporal state of data from a sensor system. A data-stream watchdog system can includes a sensor system configured to detect physical phenomena and produce corresponding output signals; a memory structure configured to store the output signals as sequential data on a repeating cycle, a watchdog code generator configured to insert a watchdog code into the stored sequential data and update the watchdog code periodically, and a data transmitter configured to receive the sequential data with included watchdog code from the memory structure and transmit the sequential data with the included watchdog code over a physical data channel each cycle of the repeating cycle. An application system receives the data and a watchdog code checker checks whether the watchdog code in the sequential data is correct and produces an error indication when the watchdog code is incorrect.
