A Review On Arbiters In Router For The Interconnection Network
Communication and Computation are two most important parameters for designing interconnect network.
Router and NI plays a crucial part when communication system is concerned. Router is responsible for traversing packet
from one PE to another hop by hop. Shared resources in router is considered very often to reduce area. When resources such
as links, buffers, and switches are shared, arbitration of the resources can create problems. In order to obtain low latency,
very fast resource allocation is required. Arbiter is crucial in allocating resources to the requesting agents. There are many
arbitration schemes proposed such as fixed priority, round robin, variable priority and many more. This paper compares
these three arbiters and analyze the synthesis results.
