The current generation of radiation-hardened general-purpose processors, such as the RAD750, lag far behind their commercial counterparts in terms of performance. To combat this, a new many-core processor was designed that would allow space applications to leverage up to 49 general-purpose processing cores for high performance space applications. The Maestro processor, based on Tilera's TILE64 chip, is the result of this effort. Maestro is rad-hard by design, but there is still the possibility of both hardware and software errors.
