13 years agocyclone II decompression rbf
Does exists description how of decompressing (or compressing) algoritm wich is used in CYCLONE II with EPCS1 (active configuration)? I spent all day but searching, I found altera's patents but it doe...

13 years agoHow about using the 4 Mb chip EPCS4 or an equivalent Serial NOR Flash (M25P40), and just leaving the bit stream uncompressed... It will take longer for the FPGA to program, but will still probably be done before your CPU is ready. If you are using true EPCS parts, it's probably cheaper to go to the larger M25P40 device.
That way you only have to use the uncompressed bitstream. Pete Pete
