| Abstract | Real-time stream processing applications, such as Software Defined Radio applications, are often executed concurrently on multiprocessor systems. A unified data flow model and analysis method have been proposed that can be used to simultaneously determine the amount of pipeline and coarse-grained data parallelism required to meet the temporal constraints of such applications. However, this unified model is only defined for Synchronous Data Flow (SDF) graphs. Defining a unified model for a more expressive model such as Cyclo-Static Data Flow (CSDF) is not possible, because auto-concurrency can cause a time-dependent order of tokens and dependencies. This paper introduces the Cyclo-Static Data Flow with Auto-concurrency (CSDFa) model. In CSDFa, tokens have indices and the consumption order of tokens is static and time-independent. This allows expressing and trading off pipeline and coarse-grained data parallelism in a single, unified model. Furthermore, we introduce a new type of circular buffer that implements the same static order as is used by the CSDFa model. The overhead of operations on this buffer is independent of the amount of auto-concurrency, which corresponds to the constant firing durations in the CSDFa model. Exploiting the trade-off between data and pipeline parallelism with the CSDFa model is demonstrated with a part of a FMCW radar processing pipeline. We show that the CSDFa model enables optimizing the balance between processing units and memory, resulting in a significant reduction of silicon area. Additionally, it is shown that reducing the maximum allowed latency increases the minimum required amount of data parallelism by up to a factor of 16. |

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.
