    摘要: Disclosed are embodiments of an integrated circuit chip designed for reliability at low ambient temperatures. The chip substrate can be divided into zones, including at least one temperature-sensitive zone (TSZ) that contains one or more temperature-sensitive circuits. Temperature sensor(s) can be positioned in the semiconductor substrate adjacent to the TSZ. Thermal radiator(s) can be embedded in a metal wiring layer and aligned above the TSZ. The temperature sensor(s) can be operatively connected to the thermal radiator(s) and can trigger operation of the thermal radiator(s) when the temperature in the TSZ is below a predetermined threshold temperature. Additionally, an on-chip power control system can be operatively connected to the thermal radiator(s) so that operation of the thermal radiator(s) is only triggered when a circuit within the TSZ is about to be powered up. Also disclosed are associated embodiments of a system and method for designing such an integrated circuit chip.

    摘要: A solution for retaining a logic state of a processor pipeline architecture are disclosed. A comparator is positioned between two stages of the processor pipeline architecture. A storage capacitor is coupled between a storage node of the comparator and a ground to store an output of the early one of the two stages. A reference logic is provided, which has the same value as the output of the early stage. A logic storing and dividing device is coupled between the reference logic and a reference node of the comparator to generate a logic at the reference node, which is a fraction of the reference logic, and to retain a logic state of the information stored on the storage capacitor. Further mechanisms are provided to determine validity of data stored in the logic storing and dividing device.

    摘要: A system is provided for securing information residing on a circuit (e.g., processor). In particular, a system and method is provided for masking electromagnetic interference (EMI) emissions emitting from a circuit using a random noise generator in combination with a low noise amplifier and antenna. The random number generator matches a frequency of a circuit to be protected, and generates a random signal to be superimposed on data. The low noise amplifier receives the random signal from the random number generator, and an antenna receives the random signal from the low noise amplifier and transmits the random signal to mask the data of the circuit to be protected.
