Abstract
In one embodiment of the invention, a method of generating a compressed configuration bitstream for a programmable logic device comprises encoding the most-prevalent data word within the configuration data of the bitstream into a codeword of a first type; encoding a set of more-prevalent data words within the configuration data into codewords of a second type; and including in the compressed bitstream at least some of the data words that are members of the set of more-prevalent data words. The included data words, when received by the programmable logic device, are adapted to be identified by the device as members of the set of more-prevalent data words. The included data words are stored for selection by the device when a codeword of the second type representing an included data word is received by the device.
