This is useful for real time applications such DAS. The USB Interface is described in VHDL which is synthesizable, implement-able and programmable on FPGA. The Xilinx ISE 8.2i is the design software suite which allowed taking the design from design entry through Xilinx device programming. The design is implemented on the Xilinx Spartan 3 (XC3S200) FPGA. The Xilinx Spartan-3 Starter Kit is used for testing the FPGA with PC using USB cable. The outshined performance of USB as compared to the previous interfaces and the reprogrammable feature and the wide use of FPGAs are the motivations for this thesisenPersonal ComputerThesis
