| Abstract | A novel method using multi-dictionary and pattern blocks is proposed for code compression to effectively reduce the memory size which program code stored. According to the repeat times of different pattern blocks and non-block codes, the code set is clustered into several clusters. Pattern blocks cluster is compressed using dictionary-based compression method and each dictionary entry points to a pattern block. The other clusters are for non-block codes and the codeword for each cluster is different. We use shorter codeword to point to the more frequently occurred cluster. By finding the best clusters for both blocked and non-block codes, the entropy of our encode strategy is high and the compression efficiency is the best. Theoretical proof and experimental results show that the compression effect of this method is superior to the traditional multi-dictionary based code compression. Code of MiBench benchmark compiled under the ARM and MIPS instruction set architecture are compressed with this method, and the average compression ratio are between 50% ~ 55%,64%~70%, separately. |

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.
