  • Secure time/date virtualization
    Patent number: 8220031
    Abstract: A system is provided that includes a processor and a system memory coupled to the processor, the system memory stores at least one application for execution by the processor. The system also includes logic coupled to the processor, the logic providing a secure time reference. The processor selectively accesses the secure time reference to generate a virtual time reference for the at least one application.
    Type: Grant
    Filed: June 28, 2007
    Date of Patent: July 10, 2012
    Assignee: Texas Instruments Incorporated
    Inventors: Guillaume Leterrier, Jerome Laurent Azema
  • System and method of identifying and preventing security violations within a computing system
    Patent number: 8220045
    Abstract: A system and method of identifying and preventing security violations within a computing system. Some exemplary embodiments may be a method comprising monitoring activity on a core bus coupled to a processor core (the processor core operating in a computing system), identifying activity on the core bus as a security violation, and preventing execution of an instruction within the processor core in response to the security violation.

  • Method and system for detecting a security violation using an error correction code
    Patent number: 7263617
    Abstract: A system and method for detecting a security violation using an error correction code. Some illustrative embodiments may be a method used in a computing system comprising reading a codeword comprising data and an error correction code (ECC) (the ECC associated with the data), deriving an error location polynomial (ELP) from the codeword, determining a total number of codeword errors from the ELP, and preventing access to the data within the codeword if the total number of codeword errors exceeds a maximum number of correctable errors.

  • Device for calibrating a pressure detector
    Patent number: 7249487
    Abstract: Device for calibrating a pressure detector, particularly an infrasonic pressure detector. This device includes measurement means for applying to this detector a reference pressure which varies depending on time and all of whose spectrum components covering a predetermined frequency range are excited simultaneously with one and the same amplitude and a zero phase shift, or a constant delay, relative to each other.

  • Device for calibrating a pressure sensor, in particular an infrasound pressure sensor
    Publication number: 20050257598
    Abstract: Device for calibrating a pressure detector, particularly an infrasonic pressure detector. This device includes measurement means (4, 6, 8, 14) for applying to this detector (2) a reference pressure which varies depending on time and all of whose spectrum components covering a predetermined frequency range are excited simultaneously with one and the same amplitude and a zero phase shift, or a constant delay, relative to each other.
