re: sensors for 333
 
Andrey Filippov , thanks for clarifying circumstances.
Then I want to concentrate on the new.
I hope that, the 5Mpix sensor profides a higher framrate at ROI.
My dream is 1280x720@50... with the remaining rolling-shutter distortion >=50fps i could live.
Please let me know, if you have experience about it.

Thanks , neat thread here...

Hi Andrey can you tell us how many MBytes/sec can transfer the next 353 model? (if you can) I'm looking for a notebook to use it so what I have to look for? 10/100 ethernet and 5400 hd is ok or I need more? the new macbook can run the live cd or not?
and about the software I've downloaded the live cd but without any camera I can't run the recording program! is there a way to view the graphic user interface (to see what can do by now and give you, if I or someone have,some ideas to make it better)? ....what I know are the pics on the wiki pages... I've look for the gui of the silicon imaging 1920... and I want to make something similar for the camera I'm planning to bild! so I've some idea for a touch screen user interface for a 7" monitor ...I don't know linux (for now) so what program I need, and to learn, to change the GUI of the elphel recording program? and is there someone that whant to help me?
Many thanks
and best reguards

What is going on!? no news from none of you!
can't wait to see new pics videos or news!

Busy with 353

5MPix boards tested, more sensors and production batch of the revised boards ordered.

Really busy now making PCB layout for the 353 that will among others accomodate IDE port (I mean - it seems to fit nicely on the board without increasing dimensions).

Come again, are you saying that you will have direct to disk recording (I am surprised)? Can you outline the features and performance of this camera?

I am considering the BBC open Dirac wavelet codec on FPGA, to see if it is a suitable target for your camera. I discovered something rather neat, and up my sort of compression alley, 3D Wavelet compression, that compresses over time as well as the screen. I have been wondering what this 3D wavelet stuff was. I understand they use wavelets in security camera applications. If it can be applied to bayer, as cineform did with their wavelet, then 100Mb/s could give 720p bayer lossless, and 1080p visually lossless. Very higher performance.

It uses newer/faster Axis ETRAX FS, slightly (20%) bigger FPGA (largest in the same size package), twice each memory (64MB video + 64MB system + 32MB flash), USB 1.1 (available in the Axis chip) and ATA-6 (routed to a high density connector so adapter will be needed to connect actual disks). System design makes use of actual bus switching in addition to pseudo-DMA channels of ETRAX - that can provide 5x bandwidth between the FPGA and the system memory.
Small 12GB HDD can fit into the current body.

wait wait...is it possible to record directly to hdd? what is the meaning of "USB 1.1 (available in the Axis chip) and ATA-6" ...we can connect a microphone for example or a video out signal through the usb is that the meaning ?!? thanks for the info
Matteo

Andrey Filippov July 20th, 2006 05:01 PM

Ata, Usb

Yes, that's the goal.

Also - yes - the easiest way to get audio in.

Don't think so - it is USB 1.1, not 2.0 and I don't know yet what will be the actual data rate from ETRAX FS available.

Awesome. Keep us posted here on dvinfo :)

Does not support S-ata, that is small connector.

But the actual performance data rate, or the compressor, and through the ata, and the drive, where do they all max out? Can all do 12.5MByte/s, or can it do more, like 20MB/s etc?

What is the current plan for this camera (seems portable) and what is current plan for compression engines?

This looks much more promising for video than current camera.

Wayne Morellini July 20th, 2006 08:38 PM

Have looked at ATA-6, needs DMA/UDMA to go above 16.6Mb/s if supported (upto 100MB/s) is this supported?

What we can look forwards to in the future, past hard disks. IBM is planning a Millipede SD memory card in the next year or so, uses atomic force microscope heads, 100GB ( I thought I read 150GB somewhere).

12GB, can be so small as to mount on the motherboard, and somebody is bound to put these things into a hard drive that uses a small laptop IDE interface.

Very good for me, as I plan game system and third world platform.

Well thanks, impressive.

I did not work with ETRAX FS yet (complete docs are available at http://developer.axis.com) so we'll see what it can provide. But compared to the current CPU it is twice faster and uses I/O coprocessor. On my side I design the hardware to use faster data transfer from FPGA to system memory (bursts of 400MB/sec, in 313/333 - 80MB/sec).

As for compressors engines - will use the same MJPEG and Theora, FPGA is just 1200K gates. I expect next year Xilinx will have something like Spartan 4 made on 65nm - then we'll be able to increase compressor performance.

Wayne Morellini July 22nd, 2006 03:04 AM

Sorry, I thought you mentioned improvements to compressor engine for next model?

I am currently finding out about an alternative FPGA design, would that be of use?

It is a big project to develop FPGA code for compressor. Theora took me some 2000 hours, Dirac will likely take more and I don't have such a window in my near future.
