    摘要: A near field communications (NFC) device is disclosed that detects a presence of another NFC capable device within its magnetic field. The NFC device provides a detection sequence having one or more detection signals to its environment. The NFC device observes the detection sequence as it is being provided to its environment to recover one or more observed detection signals. The NFC device determines a difference between the observed detection signals and one or more previous observed detection signals and/or the detection signals. The NFC device characterizes the difference as resulting from changes in the environment when the difference is linear or as resulting from another NFC capable device being present within its magnetic field when the difference is non-linear.

    摘要: Methods and apparatus are provided for generating interrupts associated with the completion of data processing. An external host may pass a first data block to a first processing engine and later pass a second data block to a second processing engine. In typical implementations, the external host expects that processing of the first data block completes first. To prevent errors and faults on the part of the external host, an interrupt associated with the processing of the second data block completing first is collapsed onto the first data block.
