  • Page-based memory access control
    Patent number: 11550482
    Abstract: A method and apparatus for controlling access to memory is disclosed. In one implementation, a memory controller may receive a memory access request that may include a virtual memory address, a device identifier (ID) and a protected access indicator. Additionally, the memory controller can receive page table entries including a physical memory address based on the virtual memory address and a security attribute associated with the physical memory address. The memory controller may access a memory based on the physical memory address, the security attribute, the protected access indicator, and the device ID.
    Type: Grant

  • Automatic placement of measurement gates
    Patent number: 8185330
    Abstract: A method and apparatus is provided for setting time positions of measurement gates on a signal under test. Signal transition data is calculated by a processor for multiple signal transitions. Measurement gate start and end positions are set relative to the multiple signal transitions based on the received signal transition data.

  • Fast correction of power measurements of signals having a changing frequency
    Patent number: 7890062
    Abstract: Power measurements of a signal having a changing frequency are corrected by acquiring samples of the signal, matching the samples of the signal to a sequence of frequencies indexed to correction transforms, and applying the correction transforms to the samples of the signal. Additionally, an apparatus corrects power measurements of a signal having a changing frequency and includes an acquisition block for acquiring samples of the signal, a sequence controller for matching the samples of the signal to a sequence of frequencies indexed to correction transforms and a correction block for applying the correction transforms to the samples of the signal.
