  • Patent number: 6658442
    Abstract: A coprocessor (200) is proposed, using a single multiplication circuit (228 and 231) coupled to a computation circuit (240) dedicated to the computation of Y0, with Y0=(X*J0)mod 2k, J0 being defined by the equation ((N*J0)+1)mod 2k=0. The computation of Y0 is done bit by bit, during one half-cycle of a clock signal before the use of each bit. A method is also proposed for the computation of a modular operation using the circuit (240) for the computation of Y0.

  • Patent number: 6560648
    Abstract: A communication system (100) includes a network, a first application running on a first Host computer system (First Host) (102) coupled to the network, and a second application running on a second Host computer system (Second Host) (122) coupled to the network.

  • Patent number: 6515304
    Abstract: An integrated circuit chip (IC) is equipped with a device for preventing reverse engineering by monitoring light emissions emitted from transistors and such electrically active devices in a circuit located in the IC. The device can be an opaque structure that blocks emissions from being detected external to the IC. Alternatively, the device can reduce light emissions from the transistors to prevent detection of the light emissions external to the IC. The device, in another alternative, can emit extraneous light emissions to hide a pattern of light emissions emitted from the transistors. As a further alternative, the device can add random delay to a signal driving the transistors to randomize the pattern of light emissions emitted from the transistors to prevent detection of a predetermined pattern of light emissions external to the IC.

  • Patent number: 6496022
    Abstract: A method and apparatus for reverse engineering an integrated circuit chip (IC chip) (120) utilizes an electrical circuit tester (114) for injecting a triggering signal into the IC chip (120) to exercise a circuit under test. In synchronization thereto, a PICA detector (116) monitors optical emissions from the circuit under test. A spatial data extractor, electrically coupled to the PICA detector, collects space information (124) from patterns of light emissions emitted by the circuit under test, and a timing data extractor, electrically coupled to the electrical circuit tester and to the PICA detector (116), collects time information (126) from the patterns of light emissions emitted by the circuit under test. A database memory (105) includes known data about the circuit under test and also includes at least one reference pattern for comparing a captured light emission pattern thereto to identify at least one circuit element in the circuit under test.

  • Patent number: 6476643
    Abstract: A micro-pipeline type asynchronous circuit and a method for detecting and correcting soft error. The asynchronous circuit records in a first recording unit a signal output by a calculation unit and then records in a second recording unit the same signal delayed by at least the duration of the pulse of a soft error. The recorded signals then are compared in a comparer circuit. If they are identical, no soft error has been detected and the output signal is recorded after another delay that is longer than the pulse duration of the soft error, and a request signal is transmitted to a control unit of a next logic stage with a delay twice as long as the pulse duration of a soft error.

  • Patent number: 6429989
    Abstract: A method for writing timing marks on a rotatable storage medium, such as on a disk in a disk drive, includes the steps of: 1) during a rotation of the disk, detecting the passage of at least a portion of a first timing mark located at a radial trajectory at a first radius of the disk, and 2) during the same rotation of the disk, writing a second timing mark at a second radius of the disk. The second timing mark is located at least one of a) where at least a portion of the second timing mark overlaps at least a portion of the radial trajectory of the first timing mark, and b) where the second timing mark is in close proximity to the radial trajectory of the first timing mark. The second timing mark is written based on different parameters such as a measured time interval, a calculated time interval, and a predetermined delay.

  • Patent number: 6424580
    Abstract: An integrated circuit includes an array of memory cells that are selected by rows and read by columns. The columns are first precharged by an internal signal to then read the memory cells. The read is responsive to an edge of a clock signal and the read is of an unknown delay. A multiplexer output provides the internal signal. The multiplexer includes a plurality of inputs electrically connected to delay lines of different delay sizes that receive the edge of the clock signal. A multiplexer control circuit selects a delay line to provide the internal signal as soon as possible after the unknown delay.
