I hate to be treated as a spammer. What is spam for me ? All your crap publications with buzzwords into them....Dear Guillaume,I've spoken to you privately (and politely) about this, and you ignored that. So, apologies, but this one is going public.This is enough. You have been spamming every newsgroup, every mailing list, me, people at Xilinx and elsewhere, with your stuff.
I'm pleased that you have an interest in FPGAs, and open flight linux, and whatever else. The world is big enough for all of these different projects.My suggestion is that you stop spamming, and actually do some work, get some code and designs up on your page, then if it's any good, people will use it.You know, I agree with your main complaint that a closed bitstream format inhibits innovation.
This is finally a good point : you agree with me on something :) !
However, it is behaviour such as yours which discourages companies like Xilinx from engaging more openly with the community.
I don't think so. Please this discussion : http://lists.duskglow.com/open-graphics/2006-October/007885.html Trade Secrets are EVIL
Please don't email me, or the lists I administer, any more, unless you have something positive and concrete to contribute.As you like to play in mood like children ( and it's not my case ), I will start my *own project*, with my *own starting code* and then I will call the *real men* .
Or to quote : http://www.deepchip.com/wiretap/060928.html "The 32 nm and 22 nm nodes are going to separate the men from the boys".Please replace this by "the hacking of the bitstream format is going..." ;) !

So, please be nice, do your homeworks and let's go the basics : to hack the bitstream format, then develop a Linux Device Driver for Reconfigurable Computing , instead of smoky publications => "OS for dynamically reconfigurable hardware" , "intrinsic evolution" : all this stuff are definitely buzzwords.*Let's do the real people, do real code* *To quote * :http://groups.google.com/group/comp.arch.fpga/browse_thread/thread/fda609f68c199c55/2c33ce4ced68b3bc?lnk=st&q=What+would+you+say%2C+if+a+CPU+manufacturer+doesn%27t+make+available%0D%0Athe+processor+documentation+(instruction+set%2C+instruction+encoding).%0D%0AHe+only+gives+you+a+C+compiler+to+design+your+software+and%0D%0Aanything+below+is+the+secret+of+the+company.+Nobody+would+buy+such%0D%0Aa+processor%2C+but+that%27s+exactly+the+situation+with+FPGA%27s.+&rnum=1#2c33ce4ced68b3bcWhat would you say, if a CPU manufacturer doesn't make available the processor documentation (instruction set, instruction encoding). He only gives you a C compiler to design your software and anything below is the secret of the company. Nobody would buy such a processor, but that's exactly the situation with FPGA's. http://xwt.org/research/megacz-fccm07.pdf In the world of FPGAs, the situation is quite dif- ferent. Since the discontinuation of the XC6200 series in 1998[17], the trend has been overwhelmingly in the direction of bitstream secrecy. Currently no major vendor discloses the bitstream format of their device. This has had the effect of stunting research in several areas, in- cluding partial reconfiguration, evolvable hardware, and fault recovery. Additionally, alternative design method- ologies such as self-timed circuitry or pausible clocks[18] become difficult to implement properly if the manufac- turer’s tools do not support themSo here is my starting point : A common philosophy ( OpenFlightLinux ), An Open Source hardware kit ( Elphel ) and a Linux Kernel Driver for Reconfigurable Hardware ( KAD )http://openflightlinux.org/helpforum/index.php?topic=65.0 I look forward to your answer, Best Regards, Guillaume___________________________ partial-reconfig mailing list partial-reconfig@xxxxxxxxxxxxxxMailing List Archive : http://www.itee.uq.edu.au/~listarch/partial-reconfig/
