| Abstract | We present the design of several so-called communication registers, which are modules that support non-blocking communication between two mutually asynchronous domains. For that purpose, a communication register offers two mutually asynchronous access ports: a write and a read port. Communication registers differ from buffers in that read and write accesses are never held up. Consequently, data may get duplicated or lost. A read access, however, always delivers a value written into the register, although not necessarily the latest one. Each of the two access ports is either clocked or self-timed, where the accesses through a self-timed port are controlled by handshakes. Therefore, one can distinguish four different kinds of modules: one for each possible access port combination. For all four cases, we give simple designs, which in several cases are subsequently refined to meet additional requirements, such as setting an upper-bound to the mutual timing interference, keeping the power consumption low, or reducing the latency. |

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.
