| Abstract | Rapid growth in the cache sizes of Chip Multiprocessors (CMPs) to support high performance applications will lead to increase in wire-delays and unexpected access latencies. NUCA architectures help in managing the capacity and access time for such larger cache designs. Static NUCA (S-NUCA) has a fixed address mapping policy whereas dynamic NUCA (D-NUCA) allows blocks to relocate nearer to the processing cores at runtime. As the blocks can map to more than one location in D-NUCA, we need efficient searching mechanism to locate the requested block. In this paper we propose a searching algorithm for D-NUCA designs in CMPs, called the HKState-NUCA (Home Knows where to find data and its state within the NUCA cache). This algorithm provides faster access to data lines compared to existing searching mechanisms. We have shown that our HKState-NUCA search mechanism reduces search requests (hop count) by about 50.89%, and achieves an average improvement of 7.04% in the hit-rate, compared to an existing searching algorithm HK-NUCA [1]. |

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.
