Characterization and parameterization of a pipeline reconfigurable FPGA

The article defines a class of architectures for pipeline reconfigurable FPGAs by parameterizing a generic model. This class of architecture is sufficiently general to allow exploration of the most important design trade-offs. The parameters include the word size and LUT size, the number of global busses and registers associated with each logic block, and the horizontal interconnect within each stripe. We have developed an area model for the architecture that allows us to quickly estimate the area of an instance of the architectural class as a function of the parameter values. We compare the estimates generated by this model to one instance of the architecture that we have designed and fabricated.
