摘要： A device has a cache memory for temporarily storing contents of a buffer memory. The device has a mirror unit coupled between the cache memory and the buffer memory. The mirror unit is arranged for providing at least two buffer mirrors at respective different buffer mirror address ranges in the main address range by adapting the memory addressing. Due to the virtual mirrors data on a respective address in any of the respective different buffer mirror address ranges is the data of the buffer memory at a corresponding address in the buffer address range. The device enables processing of a subsequent set of data in the buffer memory via the cache memory without invalidating the cache by switching to a different buffer mirror.

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： A cache-coherent multiprocessor system comprising processing units, a shared memory resource accessible by the processing units, the shared memory resource being divided into at least one shared region, at least one first region, and at least one second region, a first cache, a second cache, a coherency unit, and a monitor unit, wherein the monitor unit is adapted to generate an error signal, when the coherency unit affects the at least one first region due to a memory access from the second processing unit and/or when the coherency unit affects the at least one second region due to a memory access from the first processing unit, and a method for detecting failures in a such a cache-coherent multiprocessor system.

摘要： A method of processing data in a data processor comprising at least two data processing units. The method comprises performing different data processing steps in the data processing units concurrently during a parallel operation, and replicating performances of selected identical data processing steps in the data processing units during a non-synchronised redundant operation. The non-synchronised redundant operation comprises an initial performance of the selected identical data processing steps in one of the data processing units and a replicate performance of the data processing steps starting later than the initial performance, preferably in another of the data processing units. Initial result data representative of results from the initial performance are registered, and compared with replicate result data representative of results from the replicate performance, and an error signal is produced in case of discrepancy.

摘要： A microcontroller unit (MCU) having a functional state, a reset state, and one or more assertable fault sources is described. Each fault source has its own fault source assertion count and its own fault source assertion limit; the MCU is arranged to perform the following sequence of operations in a cyclic manner: if one or more of the fault sources are asserted, pass from the functional state to the reset state and increase the respective fault source assertion counts by one increment; if one or more of the fault source assertion counts exceeds the respective fault source assertion limit, disable the respective fault source; and pass from the reset state to the functional state. A method of operating an MCU is also disclosed.
