Improving USB 3.0 with Better I/O Management

2011 年 9 月 09 日

USB has been popular in the market for its simplicity, maturity and plug-and-play features. However, the 480 Mbps speed of USB 2.0 was not sufficient to support new generation storage and video. Therefore, the time was ripe for migration to a faster standard; this has led to the development of the new USB 3.0 protocol. The challenge that arises for developers is how to leverage USB 3.0’s full potential.  This article will explore the impact on hardware and software design to implement USB 3.0 with particular focus on handheld products. First, we will compare the capabilities of USB 2.0 and USB 3.0 and the impact of the transition on the components that interact with the USB 3.0 module.
