摘要： The disclosure relates generally to triple-redundant sequential state (TRSS) machines formed as integrated circuits on a semiconductor substrate, such as CMOS, and computerized methods and systems of designing the triple-redundant sequential state machines. Of particular focus in this disclosure are sequential state elements (SSEs) used to sample and hold bit states. The sampling and holding of bits states are synchronized by a clock signal thereby allowing for pipelining in the TRSS machines. In particular, the clock signal may oscillate between a first clock state and a second clock state to synchronize the operation of the SSE according to the timing provided by the clock states. TheSSEs has a self-correcting mechanism to protect against radiation induced soft errors. The SSE may be provided in a pipeline circuit of a TRSS machine to receive and store a bit state of bit signal generated by combinational circuits within the pipeline circuit.

摘要： This disclosure relates generally to processors and methods of operating the same. In particular, this disclosure relates to components for correcting soft errors in a processor. In one embodiment, a processor includes an instruction decoder and an exception handler. The instruction decoder is configured to receive one or more soft error correction instructions and decode the one or more soft error correction instructions. Additionally, an exception handler is configured to execute the one or more soft error correction instructions so as to correct one or more soft errors. In this manner, the processor is capable of correcting soft errors that are the result of radiation strikes.

摘要： This disclosure relates generally to computerized systems and methods of producing a physical representation of an in silico Integrated Circuit (IC) having an in silico Multi-Mode Redundant (MMR) pipeline circuit. An IC layout of the in silico IC is initially generated with the electronic design automation (EDA) program. Multi-Mode Redundant Self-Correcting Sequential State Element (MMRSCSSE) layouts are then rendered immotile while initial redundant Combinational Logic Circuit (CLC) layouts are removed from the IC layout after the MMRSCSSE layouts have been rendered immotile. By first placing the MMRSCSSE layouts and then rendering them immotile, the remaining logic can be placed again and optimized without compromising critical node spacing. As such, the described method provides for a more efficient way to create the IC layout of the in silico IC while maintaining critical node spacing.
