Abstract
In one embodiment, a method of converting an uncompressed bitstream into a compressed bitstream for a programmable logic device (PLD) is disclosed. The method includes embedding a first data frame from the uncompressed bitstream into the compressed bitstream, wherein the first data frame comprises a first data set; embedding a first instruction into the compressed bitstream to load the first data frame into a first row of configuration memory of the PLD at an address associated with the first data frame; identifying a second data frame in the uncompressed bitstream, wherein the second data frame comprises the first data set; and embedding a second instruction into the compressed bitstream to load the first data frame into a second row of the configuration memory at an address associated with the second data frame.
