| Abstract | The incredible rise in microprocessor technology has presented high speed processors and has improved the processor-memory speed gap dramatically. As a result, the design of on chip memory hierarchy is a significant issue in embedded systems. This paper describes a simulation based performance evaluation of typical cache vs. scratch-pad memory (SPM) design issues in embedded systems such as associativity and replacement policy. This evaluation is done using SimpleScalar simulation tools. Moreover, we propose the use of three replacement policies in SPM and assess the best approach for replacement in SPM for embedded systems. According to our simulation results, LRU replacement approach in SPM effectively decreases the data miss ratio of the cache. Comparisons against a SPM solution show remarkable advantages between 18% and 61% in cache miss rate for designs of the same memory size. |

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.
