In one embodiment there are provided systems and methods for detecting radio frequency interference (RFI) on a satellite that implements on-board processing. The system leverages an on-board programmable modem complex, and in some cases reprograms portions thereof, to function as an RF spectrum analyzer sensor element that captures and relays received RF information as meta-data to a ground-based system where that information can then be used, on the ground, to generate a spectral display of a received signal at the satellite.

Satellite on-board RFI detection

Techniques are provided herein to provide a processor device that has tolerance for faults associated with operations of a translation lookaside buffer. In a processor device, contents of a translation lookaside buffer are stored in a memory that is protected by an error correction code (ECC) to provide an ECC-protected backup copy of the contents of the translation lookaside buffer. When a miss exception of the translation lookaside buffer is triggered during execution of a processor function, the contents of the translation lookaside buffer is refreshed with the ECC-protected backup copy. Future operations of the processor are made using the refreshed contents of the translation lookaside buffer.
