Training Description

This USB 3.0 Architecture technical training course covers the third generation of USB – SuperSpeed USB. The increased transfer rates to 5.0Gbps, improved flow control and power management, as well as the changes to the protocol layers will be thoroughly examined. USB 2.0 is briefly reviewed because USB 3.0 is required to be completely backwards compatible.

Training Objectives

Participants attending this course will be able to:

  • Explain the required backward compatibility with USB 2.0
  • Understand the details of the new bus architecture
  • Define the new SuperSpeed data flow model
  • Indentify host and device requirements
  • Analyze actual traffic on the bus, including the different transfer types
  • Describe the new power management features
  • Implement requirements at the physical, link, and protocol layers

Prerequisites

Some understanding of the USB 2.0 specification

Who Should Attend

Hardware and software and validation engineers, system developers, technical support personnel.
