11、 this document. Configuration StratixII FPGAs support decompression of configuration data, whichsaves configuration memory space and time. This feature allows you tostore compressed configuration data in configuration devices or othermemory, and transmit this compressed bit stream to StratixIIFPGAs.

12、During configuration, the StratixIIFPGA decompresses the bit stream inreal time and programs its SRAM cells.StratixII FPGAs support decompression in the FPP (when using aMAXII device/microprocessor and flash memory), AS and PSconfiguration schemes. Decompression is not supported in the PPAconfigurat
