Abstract: Neuro Fuzzy systems, nowadays drawing attention of many researchers since being able to carry both neural networks and fuzzy logic’s benefits. Adaptive Neuro Fuzzy Inference System (ANFIS) is such a neuro fuzzy architecture which has been widely accepted since invented. It is used in different applications like universal approximator, non-linear system realization, pattern recognition etc. However, because of variety of applications, implementation of ANFIS has been turn out to be specific and same implementation barely utilized with another one. FPGAs are potential enough to bring flexibility in hardware implementation of ANFIS so as to make it generic and application-independent. In this paper, an ANFIS model designing and implementation on FPGA is described. A unique dynamic ANFIS structure is realized with VHDL which is independent of system to be realized, membership function type used. It can be easily configurable with order of ANFIS, number of inputs/outputs, and number of memb

Abstract: Practically unrestricted depth of focusing, great color saturation, high contrast ratio and high resolution in combination with various video standards are the major advantages of laser projection systems compared to conventional lamp projectors. Every individual pixel is created by collinear superposition of three collimated laser beams in the image. By result, the image stays also properly focused if the distance to the projector is varying or inclined or if curved surfaces are used as a projection screen. Here the laser wavelengths used cover more than 90% of all colors which are perceptible by the human eye. The laser displays like any other system suffers from some inherent distortions. The distortions may be in shape of pincushion, barrel, parallelogram, unequal sides, non-linearity, etc.These systems use high speed scanning in horizontal direction and in vertical direction with lower speed scanning to generate the required frame rate. High acceleration forces required for high s
