Hardwired-Clusters Partial-Crossbar: A Hierarchical Routing Architecture for Multi-FPGA Systems
Multi-FPGA systems (MFSs) are used as custom computing machines, logic emulators and rapid prototyping vehicles. A key aspect of these systems is their programmable routing architecture which is the manner in which wires, FPGAs and Field-Programmable Interconnect Devices (FPIDs) are connected. Several routing architectures for MFSs have been proposed [Arno92] [Butt92] [Hauc94] [Apti96] [Vuil96] [Babb97] and previous research has shown that the partial crossbar is one of the best existing architectures [Kim96] [Khal97]. Recently, the Hybrid Complete-Graph Partial-Crossbar Architecture (HCGP) was proposed [Khal98], which was shown to be superior to the Partial Crossbar. In this paper we propose a new routing architecture, called the Hardwired-Clusters Partial-Crossbar (HWCP) which is better suited for large MFSs implemented using multiple boards. The HWCP architecture is compared to the HCGP and Partial Crossbar and we show that it gives substantially better manufacturability. We compar...
