| Abstract | Component-based design is important for the design of complex embedded software. By properly defining component interfaces, new components can be formed by composing existing components. A newly formed component may be further composed of other components. One of the key requirements for guaranteeing the compositionality of components in real-time systems is that the composite model must be consistent with, and indistinguishable from, the interface of a primitive component so that all real-time requirements are met. In addition to being used widely for schedulability analysis on different techniques such as earliest deadline first (EDF) and rate monotonic (RM), supply-demand functions have been applied to perform compositional schedulability analysis with periodic resource models. However, supply-demand function analysis for compositional schedules has only been done for hard real-time systems guarantees. This work analyzes overloads in embedded real-time control systems with soft deadlines and the analysis helps to build a compositional system that can tolerate delays. This paper also associates the schedulability analysis with a control application using a rapid prototype implementation. |

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.
