Abstract | Several schemes have been proposed that incorporate an auxiliary buffer to improve the performance of a given size cache. Victim caching, aims to reduce the impact of conflict misses in direct-mapped caches. Victim offers competitive performance benefits, but requires a costly data path for swaps and saves between the main cache and the added buffer. Several multilateral schemes (e.g. NTS, PCS) offer competitive performance with Victim across a wide range of associativities, but require no swap/save data path. While these schemes perform well overall, their overall performance lags that of Victim when the main cache is direct-mapped. Furthermore, they also require costly hardware support, but in the form of history tables for maintaining allocation decision information. The paper introduces a multilateral cache management scheme, allocation by conflict (ABC), which generally outperforms Victim, NTS, and PCS. Furthermore, ABC has the lowest hardware requirements of any multilateral scheme-only a single additional bit per block in the main cache is required to maintain usage information for the allocation decision process, and no swap/save data path is needed. |

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.
