This paper shows the development of a 1024-point radix-4 FFT VHDL core for applications in hardware signal processing, targeting low-cost FPGA technologies. The developed core is targeted into a Xilinx ® Spartan ™-3 XC3S200 FPGA with the inclusion of a VGA display interface and an external 16-bit data acquisition system for performance evaluation purposes.(More)
—Early detection of failures in equipment is one of the most important concerns to industry. Many techniques have been developed for early failure detection in induction motors. There is the necessity of low-cost instrumentation for online multichannel measurement and analysis of vibration in the frequency domain, and this could be fixed to the machine for(More)
This paper presents an implementation of a multilayer perceptronneural network and the backpropagation learning algorithm in an FPGA. The resulting implementation, in contrast to others, is a low-cost system with effective resource utilization, capable of training the neural network for any given task. The system is based on a modular scheme conforming to a(More)
