| Abstract | In order to meet the need of high speed data transfer in ultrasonic inspection nowadays, a PC and USB based high speed digital ultrasonic flaw detector is introduce. The technology of USB (universal serial bus), especially USB2.0 facilitates the connection of PC to peripheral, and accelerates data transfer. By using the USB interface the speed of data transfer is significantly increased, which solved the real-time problem. At the same time, the PC can control the testing process, analyse the echo signal, and realize automatic testing. The use of FPGA (Field-Programmable Gate Array) decreases the volume of the circuit, improves the speed of data sampling and processing, increases the reliability, shortens the developing time, and at the same time makes modifications made to the system easier. In this paper a digital ultrasonic flaw detector specialize in inspecting rail weld, based on PC, using USB2.0 and FPGA technique is presented. The design of FPGA and the use of GPIF (general programming interface) USB transfer mode are introduced in detail. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
