need to uncompress JPEG on a picoITX / ARM board

Question

Hi all,

i want to stream jpeg images to a preferably minimal sized and easy
to handle device which will output the video stream via VGA or DVI.

Perfect would be a board/system that
- should be pico-itx sized ( maximum mini-itx )
- should be gcc programmable ( no fpga .. too complex )
- must have a 100MB / 1GB Ethernet controller on board
- must have VGA and/or DVI on board
- must be able to decompress JPEG frames of 1920x1080 in less than 40ms ( hd video )

.. Does anyone know which recent ATOM/ARM based board
can do this, or point me to a direction where
i can get this information?

.. There are not too much mini-hardware benchmarks
out there, what do i have to look for in the boards
specs to check the performance requirements?

.. is there any kind of hardware acceleration
available on these boards for jpeg decompression?
I do not want any kind of movie decompression
because of latency issues.

Thanks for sharing your experience - wendy

Here is someone who was thinking about JPEG performance. I suggest you download and experiment with your source data on PC hardware, ideally of similar speed to what you where thinking about using for your new hardware. But even if you have a PC which is much faster, you should be able to look at benchmarks and interpolate down speeds to see if your target hardware has a chance at all at hitting your goals.
