Abstract

A method for dynamically reconfiguring logic circuits on an FPGA includes the steps of: classifying a general function into sets of static functions and modal functions to be implemented on the FPGA; for each of the modal functions, generating a list of one-active actions; devising a circuit topology including at least a subset of look-up tables (LUTs) such that any one of the modal functions can be implemented at a time on the devised circuit topology; for each modal function, associating the devised circuit topology with a controller adapted to load a LUT configuration corresponding to a prescribed one of the one-active actions; implementing a single fixed circuit on the FPGA including devised circuit topologies for each of the modal functions; and updating contents of LUTs corresponding to the LUT configuration in the devised circuit topology when a change in modal function to be implemented on the FPGA is required.
