    摘要: A method for detecting a freeze-frame condition comprises receiving a sequence of images from at least one digital device; selectively encoding a first subset of the sequence of images using a first coding scheme that causes an adjustment to an image characteristic of the selected images being encoded; selectively encoding a second subset of the sequence of images using a second coding scheme; storing the first encoded subset and second encoded subset; retrieving the stored first encoded subset and second encoded subset; selectively decoding the first subset of the selected images using the first coding scheme and selectively decoding the second subset of the selected images using the second coding scheme to re-create the sequence of images. A freeze-frame condition in the re-created sequence of images is identifiable based on a plurality of decoded images being different with respect to the image characteristic across multiple decoded image frames.

    摘要: The present application relates to a signal integrity module for validating one or more control signals in time domain and a method thereof. The one or more control signals are received via a signal input from at least one control signal generating unit. A new signature is generated by a signature generating unit on the basis of a current signature and the state of the one or more control signals at a watch point. The current signature is latched into a signature register upon receiving a trigger signal. The latched signature is representative of the time course of the one or more control signals at the watch point over a monitoring period defined by the trigger signal. The latched signature is compared by a signature comparator with a pre-calculated signature to validate the integrity of the one or more control signals with respect to the time domain.

    摘要: The present application relates to an apparatus for detecting software interference and the method of operating thereof. A processor and at least one shared resource form a computing shell to execute a first, functional safety critical application and at least one second application in time-shared operation. One or more performance counters are provided to adjust a counter value in response to a performance related event. A reference value storage stores one or more threshold values, each of which is associated with one of the performance counters. A comparator receives the performance counter values, compares the performance counter values with the respective threshold values and generates at least one comparison signal in response to results of the comparisons. An interference indication generator receives the at least one comparison signal and generates at least one interference indication in response to the at least one received comparison signal.

    摘要: The invention relates to an apparatus for transfer of data elements between a bus controller, such as a CPU, and a memory controller. An address translator is arranged to receive a write address from the CPU, to modify the write address and to send the modified write address to the memory controller. An ECC calculator is arranged to receive write input data associated with the write address, from the CPU, and to generate an error correction code on the basis of the write input data. A concatenator is arranged to receive the write input data from the CPU, and to receive the error correction code from the ECC calculator, and to concatenate the write input data and the error correction code to obtain write output data, and to send the write output data to the memory controller.
