A novel system and method are provided for storing a configuration data file for a programmable logic device such as an FPGA and for loading such a file into the device. The system and method of the present invention improves the performance of a bitstream storage apparatus by compressing the bitstream by a factor of about 5:1 to 10:1 before loading the bitstream into a storage unit, and then decompressing the bitstream, preferably within the storage unit, before forwarding the bitstream to the programmable device. In one embodiment, the decompression circuit is programmable, being able to utilize any of two or more different algorithms. In this embodiment, several different compression algorithms are evaluated, and the most efficient algorithm for that particular bitstream is utilized.
