| Abstract | Centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption and are thus not suitable for consumer electronic devices. The consequence is the emergence of architectures having many interconnected clusters each with a separate register file and a few functional units. Among the many inter-cluster communication models proposed, the extended operand model extends some of operand fields of instruction with a cluster specifier and allows an instruction to read some of the operands from other clusters without any extra cost.Scheduling for clustered processors involves spatial concerns (where to schedule) as well as temporal concerns (when to schedule). A scheduler is responsible for resolving the conflicting requirements of aggressively exploiting the parallelism offered by hardware and limiting the communication among clusters to available slots. This paper proposes an integrated spatial and temporal scheduling algorithm for extended operand clustered VLIW processors and evaluates its effectiveness in improving the run time performance of the code without code size penalty. |

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.
