The authors present a modified Tank and Hopfield neural network for solving the problem of cell placement in integrated circuits, a constrained optimization problem that is NP-complete. The neural network is composed of two mutually interconnected subcircuits. One determines the configuration of cells on the plane for which the bounding box area and(More)
In this paper we present a VHDL-based design methodology which we adopted in the design of an ASIC chip for real time image analysis in a quality control industrial environment. The design methodology is based on the following considerations: i) we explored the design space by applying some high level transformations on the VHDL specications; ii) we dened(More)
This document presents an applicability of existing MPLS protection mechanisms, both local and end-to-end, to the MPLS Transport Profile (MPLS-TP) in ring topologies. This document does not propose any new mechanisms or protocols. Requirements for MPLS-TP protection especially for protection in ring topologies are discussed in "Requirements of an MPLS(More)
This document describes requirements for, and the use of, the Generalized Multi-Protocol Label Switching (GMPLS) control plane in support of the Virtual Concatenation (VCAT) layer 1 inverse multiplexing data plane mechanism and its companion Link Capacity Adjustment Scheme (LCAS). LCAS can be used for hitless dynamic resizing of the inverse multiplex group.(More)
Recently an isotropic resistive network that performs a Gaussian ltering of an image for pre-processing tasks in image analysis has been proposed. In this paper, starting from biological considerations on cortical organization, we propose an anisotropic resistive network able to extract local features of an image, that can be used to detect variations of(More)
The authors present modifications to Kohonen autoassociative maps to increase their efficiency for clustering and decrease their sensitivity to initial conditions. A new update rule is described for the classification for similarity. Some test results are presented for comparison between different algorithms. The new neural network algorithm was applied to(More)
