    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).

    摘要: A filter for filtering n data trains by time division multiplexing includes data channels for receiving data train values, registers subdivided into n groups for buffer storage of the data train values or derived values, and adders each having inputs. Each of the n groups is connected to one of the data channels. The adders and the registers alternatively connect to form a chain. The first input of respective adders connected upstream of a respective register of an ith group (0≦i≦n−1) has a connection to respective data channels assigned to the ith group, and the second input is connected to a respective register of a group having a number (i−1)mod n without an intervening register of another group. The filter is used to parallelly decimate data trains by a common factor. A filter configuration includes the filter and two multipliers. A method is also provided.

    摘要: In order to be able to use a smaller routing table (4) and, thus, to reduce the costs and power consumption and to improve the performance of an IP router, it is proposed to extract a destination address identifier (ADR) from a data packet to be forwarded by the IP router, compress the extracted destination address identifier (ADR) by using a lossless data compression algorithm, and compare the compressed destination address identifier with entries stored in the routing table (4) so as to find a correspondence between the destination address identifier and one of the entries of the routing table (4). Each entry of the routing table (4) corresponds to a possible or available forwarding address of the IP router, the forwarding addresses having been compressed with the same data compression algorithm as the destination address identifier. After having found a correspondence between the destination address identifier and one of the compressed forwarding addresses stored in the routing table (4), a switch (6) of the IP router switches the respective data packet to one of its output links (OUT) which is associated with the respective forwarding address matching the destination address identifier (ADR).

    摘要: A method and a programmable unit for bit field shifting in a memory device in a programmable unit as a result of the execution of an instruction, in which a bit segment is shifted within a first memory unit to a second memory unit, are presented. The bit segment is read with a first bit length from a first bit field in the first memory unit starting at a first start point. The bit segment that has been read is stored in the first bit field in the second memory unit starting at a second start point. The first or the second start points is updated by a predetermined value and the updated start point is stored for subsequent method steps.

    摘要: In orthogonal frequency division modulation, use is made of the fact that the individual carriers which are transmitted on the principle of frequency multiplexing are orthogonal to one another. The modulation can then be carried out relatively simply using discrete Fourier transformation. Sicne the calculation of the discrete Fourier transformation involves a large number of multiplications, the bit data which are intended to be modulated onto the carriers are combined in each case to form a two-dimensional vector. The vector is supplied to a two-dimensional inverse Fourier transformation as the input variable. The number of multiplications required is thus reduced. The invention is particularly suitable for transmission of broadcast radio, television and mobile radio signals.
