デジタル信号処理
Digital signal processing (DSP) is a ubiquitous methodology in scientific and engineering computations. However, practically, DSP problems are often not only 1-D. For instance, image data are 2-D signals and radar signals are 3-D signals. While the number of dimension increases, the time and/or storage complexity of processing digital signals grow dramatically. Therefore, solving DSP problems in real-time is extremely difficult in reality.
