Abstract
Various techniques are provided to compress and decompress configuration data for use with programmable logic devices (PLDs). In one example, a method includes embedding a first data frame comprising a data set from an uncompressed bitstream into a compressed bitstream. The method also includes embedding a first instruction to instruct a PLD to load the first data frame into a data shift register, embedding a second instruction to instruct the PLD to load a first address associated with the first data frame into an address shift register, and embedding a third instruction to instruct the PLD to load the first data frame from the data shift register into a first row of a configuration memory corresponding to the first address. The method further includes identifying a second data frame comprising the data set in the uncompressed bitstream, and embedding fourth and fifth instructions in place of the second data frame.
