Routing architecture and algorithms for superconductivity circuits-based computing hardware

the 24th Canadian Conference on Electrical and Computer Engineering (CCECE 2011) : Niagara Falls, Ontario, Canada : 8-11 May, 2011Dedicated tools for placing and routing data flow graphs extracted from computation-intensive applications are basic requirements for developing applications on a large-scale reconfigurable data-path processor (LSRDP) implemented by superconductivity circuits. Using an alternative technology instead of CMOS circuits for implementing such hardware entails considering particular constraints and conditions from the architecture and tools development perspectives. The main contribution of this work is to introduce an operand routing network (ORN) architecture as well as algorithms for routing the nets corresponding to the edges of the data flow graphs. Further, a micro-routing algorithm is proposed for routing and configuring the ORNs internally. These algorithms have been applied on a number of data flow graphs from target applications and the results demonstrate their efficacy
