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
