    摘要: A method, system on a chip, and computer system for generating more robust keys which utilize data occupying relatively small die areas is disclosed. Embodiments provide a convenient and effective mechanism for generating a key for use in securing data on a portable electronic device, where the key is generated from repurposed data and a relatively small amount. A multi-stage encryption algorithm may be performed to generate the key, where the first stage may include encrypting the secure data, and the second stage may include encrypting the result of a logical operation on the encrypted secure data with a unique identifier of the portable electronic device. A secret key may be used as the encryption key for each stage. The result of the second encryption stage may include the generated key which may be used to perform subsequent operations on the portable electronic device.

    摘要: A method and system and related computer program products are described for identifying an object of service comprising the initial step of generating and storing a static composite identifier representing a state of the object of service. Then, whenever it is desired to identify the object of service, the steps are carried out of: generating a dynamic composite identifier representing a current state of the object of service; locating and retrieving the stored static composite identifier, and searching a database for a match with an object of service recorded therein using either the static or the dynamic composite identifiers, or both.

    摘要: One embodiment of the present invention sets forth a technique for reducing the copying of data between memory allocated to a primary processor and a coprocessor is disclosed. The system memory is aliased as device memory to allow the coprocessor and the primary processor to share the same portion of memory. Either device may write and/or read the shared portion of memory to transfer data between the devices rather than copying data from a portion of memory that is only accessible by one device to a different portion of memory that is only accessible by the other device. Removal of the need for explicit primary processor memory to coprocessor memory and coprocessor memory to primary processor memory copies improves the performance of the application and reduces physical memory requirements for the application since one portion of memory is shared rather than allocating separate private portions of memory.

    摘要: A combustion device for an exhaust treatment system is disclosed. The combustion device may have a fuel injector configured to inject fuel toward an exhaust flow. The combustion device may also have an ignition source configured to ignite the injected fuel. The combustion device may further have a deflector configured to redirect at least a portion of the ignited fuel towards a center of the exhaust flow.
