Masters Theses

Abstract

"This thesis describes the Field Programmable Gate Array (FPGA) implementations of two powerful techniques of Computational Intelligence (CI), the Particle Swarm Optimization algorithm (PSO) and the Neural Network (NN). Particle Swarm Optimization (PSO) is a popular population-based optimization algorithm. While PSO has been shown to perform well in a large variety of problems, PSO is typically implemented in software. Population-based optimization algorithms such as PSO are well suited for execution in parallel stages. This allows PSO to be implemented directly in hardware and achieve much faster execution times than possible in software. In this thesis, a pipelined architecture for hardware PSO implementation is presented. Benchmark functions solved by software and FPGA hardware PSO implementations are compared. NNs are inherently parallel, with each layer of neurons processing incoming data independently of each other. While general purpose processors have reached impressive processing speeds, they still cannot fully exploit this inherent parallelism due to their sequential architecture. In order to achieve the high neural network throughput needed for real-time applications, a custom hardware design is needed. In this thesis, a digital implementation of an NN is developed for FPGA implementation. The hardware PSO implementation is designed using only VHDL, while the NN hardware implementation is designed using Xilinx System Generator. Both designs are synthesized using Xilinx ISE and implemented on the Xilinx Virtex-II Pro FPGA Development Kit"--Abstract, page iii.
