摘要： An inappropriate-access module is incorporated in a computer system along with other computer system modules. The inappropriate-access module is connected to a read address decoder and controlling logic located within various other modules. The inappropriate-access module detects inappropriate read accesses or the occurrence of the inappropriate access during operations performed on related sensitive system resources in accompanying computer system modules. The inappropriate-access module produces an inappropriate-access flag, made available to the rest of the system, which invokes responses in the accompanying modules such as a halt in processing and protective measures for system resources. Additionally, a related logic block is able to detect the inappropriate access and produce an inappropriate-access trigger which causes a halt to processing within the logic block as well as in related system modules.

摘要： A scrambler/descrambler module included in an integrated circuit device is operable for receiving a scrambling key and constant data that is unique to the integrated circuit device. The scrambler/descrambler module includes a first layer or circuit arrangement that uses a scrambling key to generate first scrambled data. The scrambler/descrambler module includes a second layer or second circuit arrangement that uses data that is unique to the integrated circuit device, and that is constant over the life of the integrated circuit device, to scramble the first scrambled data to generate second scrambled data.

摘要： The disclosed quadrature decoder filtering circuitry for motor control uses one quadrature signal to correct an error in the other quadrature signal, thus allowing a noisy signal due to large dust particles or scratches to be recovered. In some implementations, a system processing for quadrature signals comprises a first circuitry triggered by edges of a first quadrature signal to detect inactivity of a second quadrature signal during consecutive edges of the first quadrature signal. A second circuitry is operable to count the number of consecutive edges of the first quadrature signal during inactivity of the second quadrature signal. A third circuitry is operable to combine transitions of the first quadrature signal with the second quadrature signal during a period of time determined by the count value of the second circuitry.

摘要： A variable architecture for random number generators is disclosed. In some implementations, the architecture of a random number generator may be varied based on microcontroller-specific data stored on the microcontroller. For example, a random number generator module may be embedded in a microcontroller circuit. The random number generator module may be designed to receive input from data sources in the circuit that contain microcontroller-specific data (e.g., a unique chip identifier, data carried in fuse bits). In some implementations, the architecture of the random number generator module may be adjusted or varied based on the microcontroller-specific data.
