| Abstract | Today's technology is changing and improving at such a rapid rate that even the most state of the art systems seem to be obsolete before completion. Sometimes, changing customer requirements dictate that a smaller, faster, and more powerful system be produced to perform the same tasks. Target migration, the transfer of a software product from one target system to another more powerful target system, is one cost effective way to upgrade system performance.Target migration requires careful analysis to determine the impact of the new target environment on system performance. In many cases, the goal of target migration is to improve processor loading and throughput, while reducing memory requirements. A specific methodology needs to be established that will enable the design team to perform the required analysis and then be able to identify and measure the improvements on the system performance and memory usage. This methodology must be established early by the design team and then followed through all phases of the target migration effort.This paper describes methodology used by a Martin Marietta (formerly GE Aerospace) design team that was asked to determine the impact of a target migration to the MIL-STD-1750A Architecture. The methodology is divided into three phases. The steps to be performed in each phase are described and examples are provided from an actual project. The lessons learned from our experiences with this new methodology will benefit other design teams tasked with migrating existing software products to smaller but more powerful target systems. |

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.
