Improving the Throughput of Asynchronous On-chip Networks with SDM

چکیده
Asynchronous quasi-delay-insensitive (QDI) NoCs have several advantages over their clocked counterparts. Virtual channel (VC) is the most utilized flow control method in asynchronous routers but spatial division multiplexing (SDM) achieves better throughput performance for best effort traffic than VC. A novel asynchronous SDM router architecture is presented. Area and latency models are provided to analyse the network performance of all router architectures including wormhole, virtual channel and SDM. Network performance shows that SDM routers outperform VC routers in both throughput and area overhead.

Using Clos Switches in Area Efficient Asynchronous SDM Routers
Most of current asynchronous on-chip routers use the virtual channel flow control method which compromises throughput and latency. Instead of using virtual channels, an asynchronous spatial division multiplexing (SDM) router has been proposed recently. The major design overhead of an SDM router is the enlarged central switch which increases proportionally to the number of virtual circuits. Clos...

متن کاملA Differentiated Pricing Framework for Improving the Performance of the Elastic Traffics in Data Networks
Rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. Most commonly used algorithm in end hosts is TCP. This is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. Moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by TCP affect other sessions...
