An architecture for real-time design of the system for multidimensional signal analysis

Multiple clock cycle hardware implementation (MCI) of a flexible system for space/spatial-frequency signal analysis is proposed. Designed special purpose hardware can realize almost all commonly used two-dimensional space/spatial-frequency distributions (2-D S/SFDs) based on the 2-D Short-time Fourier transformation (2-D STFT) elements. The flexibility and the ability of sharing functional kernel, known as STFT-to-SM gateway, [1], within S/SFDs execution, represent major advantages of this approach. These abilities enable one to optimize critical design performances of the multidimensional system, such as hardware complexity, energy consumption, and cost.
