Abstract: On-going improvements in the scaling of FPGA device sizes and timeto-market pressures motivate the adoption of a module-oriented design flow. Economic factors encourage the reuse of smaller devices for high performance computational tasks. Like other researchers, we therefore envisage a need for dynamic reconfiguration of FPGAs at the module level. However, previous proposals have not focussed on the communications issues raised by dynamic module-based reconfiguration. This paper proposes a methodology for the rapid deployment of a communications infrastructure that supports the communications needs of dynamic modules when these are known at design time while allowing some flexibility for a range of unknown communication requirements to be met at run time. 1
