| Abstract | The demand of greater speed in USB communication has given birth to 4th generation standard named Super Speed USB with 10 times increase in the data rate compared to High Speed USB. Super speed USB introduces a variety of features that improve performance, reduce system power consumption and extend functionality. In order to support all these enhanced features afforded by USB3 specifications, a new generation of host controller is required. The implementation of this host controller standard is described in hardware by XHCI (Extensive host controller interface) which is quite complex and different from previous generations with its difficult terminology and modeling. In order to handle this controller, indepth understanding of each data structure is required. This paper attempts to create an analogy between the phenomenon of XHCI and its previous generation candidate, EHCI, by analyzing their data structures and operational models. This analysis will help in comprehending the programming model of XHCI quite easily and will reduce the USB system development cycle time. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
