Using channel pipelining in reconfigurable interconnection networks

چکیده
The major problem in wormhole routing networks is related with the contention due to message blocking. Reconfigurable networks are an alternative to reduce the negative effect that congestion produces on the performance of the network. Our work is focused on dynamic reconfiguration. This technique consists basically of placing the different processors in the network in those positions which, at each computational moment and according to the existing communication pattern among them, are more adequate for the development of such computation. In a reconfigurable architecture, the clock period is determined by the transmission time across the switch. To increase this frequency the channel pipelined technique is used. In this paper we present the foundations of reconfigurable network architecture. We show the general structure of the reconfigurable systems and we indicate the characteristics of the channel pipelining technique. Finally, we evaluate the performance of a reconfigurable system.

متن کاملTROUTE: A Reconfigurability-Aware FPGA Router
Since FPGAs are inherently reconfigurable, making FPGA designs generic does not reduce chip cost, as is the case for ASICs. However, designing and mapping lots of specialized FPGA designs introduces an extra EDA cost. We describe a two staged fully automatic FPGA tool flow that efficiently maps a generic HDL design to multiple specialized FPGA configurations. The mapping is fast enough to be ex...
