Modern System-on-Chip (SoC) design relies heavily on efficient interconnects like Networks-on-Chip (NoCs). They provide an effective, flexible and cost efficient way of communication exchange between the individual processing elements of the SoC. Therefore, the choice of topology and design of the NoC itself plays a crucial role in the performance of the(More)
Networks-on-Chip (NoCs) enable cost-efficient and effective communication between the processing elements inside modern systems-on-chip (SoCs). NoCs with regular topologies such as meshes, tori, rings, and trees are well suited for general-purpose many core SoCs. These topologies might prove suboptimal for SoCs with predefined application characteristics(More)
—Custom network-on-chip (NoC) structures have improved power and area metrics compared to regular NoC topolo-gies for application-specific systems-on-a-chip (SoCs). The synthesis of an application-specific NoC is a combinatorial problem. This paper presents a novel heuristic for solving the routing path allocation step. Its main advantages are the support(More)
In this paper is presented a method for invariant 2D object representation based on the Mellin-Fourier Transform (MFT), modified for the application. The so obtained image representation is invariant against 2D rotation, scaling, and translation change (RST). The representation is additionally made invariant to significant contrast and illumination changes.(More)
The paper presents a new method for extracting and positioning contours of moving objects. The method is applicable in the surveillance of elderly individuals and facilitates the detection of critical situations when the elderly individuals find themselves in need of immediate help. For this, single frames from the video sequence are extracted in regular(More)
In this paper is offered a method for non-linear still image representation based on pyramidal decomposition with a neural network. This approach is developed by analogy with the hypothesis for the way humans do image recognition using consecutive approximations with increasing similarity. A hierarchical decomposition, named Inverse Difference Pyramid(More)
In the paper is presented a new approach for solving some of the authentication problems in large computer systems, communication networks and mobile communications, using a new method for lossless compression of some kinds of biometric information (fingerprints and signature images). The image processing is based on two-level Inverse Difference Pyramid(More)
In the paper is offered a new approach for blocking artifacts reduction in still images, processed with 2-level IDP Inverse Difference Pyramid (IDP) decomposition, based on DCT and Walsh-Hadamard orthogonal transforms. For this purpose was developed a two-dimensional fuzzy digital filter, whose performance changes in accordance with the image contents,(More)
In the paper is presented a specific approach aimed at the improvement of the visual quality of underexposed or low-contrast images. For this is developed a new contrast-enhancement algorithm based on the segmentation of the image area with relatively high density of dark elements. The problem is solved changing the brightness intervals of the selected(More)
