You can get the real thing from
www.mechtronicbrick.dk ==> www.mechatronicbrick.dk
www.ronetix.ch ==> http://www.ronetix.at/
www.cogcomp.com
www.iotech.dk
www.liab.dk
I could not get some of these links to work. But the others gave some
good results. Cogent has a 520 MHz PXA270 module for only $50 more
than the SAM9260 module. Way better deal and a *HUGH* increase in
speed! I have been looking for something like this.
Funny, I remember communicating with a guy recently which
balked at $600 price for a development kit with Ethernet
and $975 for DevKit with Ethernet and LCD screen.
The PXA270 DIMM is $399 DIMM in single qty.
If you want to get a single DIMM with baseboard, it is $1499.
With QVGA LCD = $1799..
If you need VGA or better resolution, then a dual bus system
like the www.iotech.dk module and the AT91RM9200 is
probably faster than the PXA, since you do not steal bandwidth
from the CPU and you have several interesting accelerators.
The VGA controller, they have implemented in the FPGA
collects windows on the fly, so no heavy bitblt in the processor
just to move windows, or handle overlapping windows.
The AT91SAM9263, which is likely to soon be available from
a number of module companies, also has a dual bus structure
so you can have pretty large screens without affecting the CPU
performance.
The Ronetix module has a complete frame buffer inside, and
if you make all redraws in this for a QVGA screen,
you have up to 800 MB/s bandwidth to the memory.
The effect is about 2 x performance compared to
doing draws to SDRAM.
MHz is not everything.
The I/O tech has 8 MB Flash and 16 MB SDRAM and sells for 68 Euro@1k
You can get it with up to 16 MB flash and 64 MB SDRAM
There is also an FPGA option with Spartan III (up to 1.2 Mgates)
and another 64 MB SDRAM, all for 149 Euro@1k
