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 graphic character that has a character matrix with a number of character units that are indivisible at least in either a horizontal direction or a vertical direction is scaled by dividing the character matrix into one first and at least one second character segment, each comprising at least one of the character units. The first character segment is symmetrically scaled using a first scaling factor and the second character segment is scaled using a second scaling factor different from the first scaling factor.

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 data logging system for logging input data received from a data source is described. The data logging system has a data storage memory. A data input is arranged to repeatedly receive input data having a temporal input data resolution. A write controller is arranged to write newly received input data as received via the data input into the data storage memory. The writing comprises writing the newly received input data at the temporal input data resolution. The writing comprises keeping recent data at the temporal input data resolution in the data storage memory, and overwriting part of old data with newly received input data while keeping another part of the old data in the data storage memory at lower data resolution.

摘要： To determine the noise contained in a picture, it is proposed first to determine homogeneous picture regions of the picture (100-102) and then to measure the high-frequency signal component in these homogeneous picture regions (BR). The measurement of the high-frequency signal components is here averaged over many measurement points, i.e. over many homogenous picture regions (BR), and is processed into a noise figure (NOISE_SUM) (103-104). In this way, the quality of the picture can be measured directly in the picture content.

摘要： The invention relates to a method for changing the image size of video images, in which a decimation of video image signals (V) by an integral decimation factor (MHD, MVD) is carried out, and the decimated video image signals are subsequently read into an image memory for buffering.In order to achieve better possibilities of adjusting the image reduction with a relatively low outlay and high image quality, a fine decimation of the video image signals (V) is additionally carried out before buffering by a fine decimation factor (SHS, SVS) which can be adjusted to non-integral values, and a total decimation factor (MH, MV) relevant to the decimation of the video image signals (V) is formed from the integral decimation factor (MHD, MVD) and the fine decimation factor (SHS, SVS).
