Abstract: The present invention pertains to electronics (circuits and systems comprising such circuits, specifically like tiled multi- and manycore systems) for use in increased radiation environments. The invention provides (operating) methods and apparatuses (systems) for mitigating radiation effects in the (main) circuits (also denoted tiles) defining these apparatuses by adapting those or providing those with additional building blocks, enabling use of a depowering technique The invention also mitigates radiation effects in those building blocks (circuits or subcircuits) of the apparatuses themselves. The invention enables to retain full functionality on those resources of the chip that are not currently undergoing a depowering cycle, hence avoids power cycling those all simultaneously.
