IntroductionIntroduction What is USB ?
Universal Serial BUS is a standard for multiple tasks which can be concluded by two words: Data Transfers
Why USB?The most important reasons (among
others):1. The same connector type for
different devices2. Speed3. Chaining
MotivationMotivation
USB 2.0 supports both L.S and F.S of the USB 1.1 adding to it the High Speed of 480 Mbps
USB 2.0 never reaches the speed it claims to posses

Future StepsFuture Steps
Until now we have mostly done a lot of research
Nowadays we are studying the manuals of the FPGA and the Nios II processor programming
The next step will be setting the architecture and design
