| Abstract | Since the first microprocessor, built in 1971, micro-processors have evolved at a dramatic pace in terms of technology, processing power, dissipation, and functionality. This paper makes a brief overview of the history, presents major areas of importance in design and summarisizes some approaches that are currently being considered for the future. The 4 bit 4004 from INTEL CORP. was the first micro-programmable computer on a chip. It consisted of a 4 bit parallel adder, 16 bit registers, an accumulator and a stack on a single chip. Being able to execute 45 instructions, the chip contained 2300 transistors. In the early days microprocessors were programmed in machine language; however, the quick evolution of superior system architectures and superior high level language availability caused an explosion in the domain of microprocessor usage. MOORE's law which states that the number of transistors integrated on a piece of silicon generally doubles every two years has been maintained practically for the microprocessor. In the initial times, Memory, Input/Output, Timer, and other special functions were found on separate chips. As the Technology of processing improved it became possible to pattern much finer geometries on silicon, therefore, either more powerful computers with sophisticated functions could be built economically or the existing Microprocessor became affordable for a vast spectrum of applications such as in toys, TV, automotive, instrumentation, CAD/CAM tools, telecommunication, smart cards, personal computers etc.. A microprocessor is a central arithmetic and logic unit of a computer. |

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.
