Abstract: A data processing device provides for registers which can be formatted as segments containing numbers to which operations can be applied in SIMD fashion. In addition it is possible to perform operations which combine different segments of one register or segments at different positions in the different registers. By providing specially selected it is thus made possible to perform multidimensional separable transformations (like the 2-dimensional IDCT) without transposing the numbers in the registers.

Abstract: A data processor has a debug circuit arranged to monitor whether operand data used for execution of a program meets a debug exception condition. The debug exception condition tests a two or more of multi-bit subfields of a vector operand independently. Debug action is taken if one or more of the multi-bit subfields meet the corresponding conditions.

Abstract: Video is processed based on the color content of a video frame. A frame-specific or sequence-specific color cube is created in order to efficiently use the available bandwidth, and to efficiently carry out conventional video operations. The color cube is a statistically tuned subset of the original color space.

Abstract: A video apparatus includes a circuit for reducing noise in applied input video signals. The noise reducing circuit is provided with a temporal noise filter (S1, LUT, M), a down-sample unit (D) for obtaining a spatial down-sampling of video signals (Vi) of subsequent pixels, these down-sampled video signals being supplied to the temporal noise filter (S1, LUT, M), and an up-sample unit (U) for generating, in response to noise output signals obtained in the temporal noise filter (S1, LUT, M), noise signals of the pixels, and a subtractor (S2) for subtracting the noise signals from the respective input video signals (Vi).
