| Abstract | To meet the requirement of high-speed data processing of complicated system with multi-sensor inputs and multi-controller outputs, an embedded ARM+FPGA +DSP multiprocessor platform is designed, which is characterized by synchronous cooperation and mutual exchange of shared data. ARM completes interface expansion and task scheduling configuring peripheral interfaces including RS422, CAN and RJ45, and it loads program into the 3 DSPs via HPI bus. Shared data stored in multi FIFO core sets in FPGA can be transmitted between any two processors controlled synchronously by interrupt signal. The interrupt signal from ARM starts a new turn of operation, in which period all processors exchange necessary shared data mutually, after ARM collecting 3 DSP interrupt signals, it means the end of this turn and the beginning of next operation cycle. With characters of high-speed, synchronization and real-time, this system platform is designed for the semi-physical simulation system suitable for the on-orbit spacecraft ground test. The principle and frame have reference value for navigation computer upgrading improvement. |

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.
