| Abstract | In recent years, many systolic algorithms have been proposed as solutions to computationally demanding problems in signal and image processing and other areas. Such algorithms exploit the regularity and parallelism of problems to achieve high performance and low I/O requirements. Since systolic algorithms generally consist of a few types of simple processors, or systolic cells, connected in a regular pattern, they are less expensive to design and implement than more general machines. This advantage is offset by the fact that a particular systolic system can generally be used only on a narrow set of problems, and thus design cost cannot be amortized over a large number of units. One way to approach this problem is to provide a programmable systolic chip (PSC), many copies of which can be connected and programmed to implement many systolic algorithms. The systolic environment, by virtue of its emphasis on continuous, regular flow of data and fairly simple per-cell processing, imposes new design requirements for programmable processors which are quite different from those found in a general-purpose system. This paper describes the CMU PSC, a single-chip microprocessor suitable for use in groups of tens or hundreds for the efficient implementation of a broad variety of systolic arrays. The processor has been fabricated in nMOS, and is undergoing testing. |

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.
