Design and implementation of a digital system on FPGA

This report covers the implementation of digital system design using Field Programmable Gate Array (FPGA). Universal Serial Bus (USB) has become a widely adopted digital system that can be found in many products. It has become a common standard to replace older communications protocol whenever a device needs to be connected to the computer. USB is versatile as it has four different transfer types. Each of the transfer type is use for different purpose like bulk transfer is use for transferring of huge data payload; an example would be a printer and interrupt transfer is use for low data device, for example, a computer mouse. In order to implement the design, the design is broken down into smaller components and simulated. The design is broke down into three main components, the receiver, transmitter and the controller components. In each of the components there are smaller blocks that is use to perform certain functions, like NRZI decoding. In the overall design, all the components are integrated together to meet the USB specification. FPGA provide a method to create a “system on chip” where part of the FPGA can be use to build the USB protocol to interface with the external world and another part to provide the design system required.Bachelor of Engineerin
