  • Memory access control
    Patent number: 9418212
    Abstract: An apparatus comprising: a memory having at least two sections; a security element associated with at least one of said at least two sections; and a processor for controlling access to at least one of the at least two sections of the memory in dependence on a value of the security element. The apparatus may be an integrated circuit and the memory may be a read-only-memory storing generic code in one of the sections and code specific to a mobile communication device provider in the second section. The security element may be a permanently programmed memory element programmed by the IC manufacturer.
    Type: Grant

  • Method and device for synchronizing integrated circuits
    Patent number: 7127632
    Abstract: A method and device for synchronizing the time between at least two integrated circuits (201, 202), which receive the same pulse signal. In the integrated circuits (201, 202) a counter (204, 206) is used to count the number of pulses in the received pulse signal to synchronize the common time between said integrated circuits.

  • Display frame buffer update method and device
    Patent number: 6909434
    Abstract: A method for updating an integrated display frame buffer of a display module in a mobile electronic device, comprising a local frame buffer and a processor, comprising the steps of transferring display information to said local frame buffer, updating said display frame buffer by transferring said display information from said local frame buffer to said display frame buffer, and displaying said display information on said display module. Furthermore, the invention comprises the additional steps of detecting changes of said display information stored in said local frame buffer, and updating said display frame buffer when a change of said display information in said local frame buffer is detected.
