A Worst Case Performance Model for TDM Virtual Circuit in NoCs

چکیده
In Network-on-Chip (NoC), Time-Division-Mutiplexing(TDM) Virtual Circuit (VC) is well recognized as being capable to provide guaranteed services in both latency and bandwidth. We propose a method of modeling TDM based VC by using Network Calculus. We derive a tight upper bound of end-to-end delay and buffer requirement for indivdual VC. The performance analysis using Latency-Rate server is also presented in comparsion with our Performance model for TDM Virtual Circuit in NoCs (Pemvin). We conducted experiments on comparing Pemvin to the Latency-Rate server model. Our experiment results show the improvement of Pemvin on tightening the upper bound of end-to-end delay and buffer requirement.

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 provide...
