Position-based weighted round-robin arbitration for equality of service in many-core network-on-chips

Content Provider ACM Digital Library
Author Park, Hanmin Choi, Kiyoung
Abstract This paper presents the position-based weighted round-robin arbitration for equality of service in many-core network-on-chips employing a deterministic routing algorithm. We concentrate on the network saturation induced by the hot-spot traffic that occurs when the threads running on the system simultaneously access shared data, global shared locks, etc. It exploits the deterministic properties of the interconnect network---the topology and the routing algorithm. This leads to the omission of additional information in packet headers, compared to the previous approaches. The hardware overhead is minimal, requiring only the weight counters in addition to a typical round-robin arbiter. Compared with the previous work, the proposed algorithm also reduces the critical path delay due to its simplicity. Although designed against the hot-spot traffic, the proposed arbitration scheme shows little performance degradation under other traffic patterns in terms of the average latency and the saturation throughput.

About National Digital Library of India (NDLI)
NDLI logo

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.
