An i.mx31, philips LPC, omap 3430 or BCM2820 would be a lot more usefull and faster because those have a VFP unit.

So, between those three, what are the most open? Someone *cough* needs to decide soon what CPU to base his next platform on...

From the list above you can forget about philips and broadcom about being open.

Wait till the prices for 8GB microdrives drop
[div align=\"right\"][a href=\"index.php?act=findpost&pid=146068\"][{POST_SNAPBACK}][/a][/div]

I'm waiting delivery of a 3100.. in a way I am happier with a 3100 than 3200 because of it's overclockability (if there's such a word), and if I want more than 4GB internally I'll wait for 8GB compact flash cards to become a reasonable price. I've seen 4GB CF cards for less than GBP60 now, and 8GB ones for less than GBP180 so it won't be too long before it's not an expensive option.

I think the 20GB drives are around but hitachi are selling them for the hidef camcorders. Anyone found a place that sells them yet?

http://www.tgdaily.com/2006/11/29/marvell_...hans_processor/

Some more update:

There is much more potential in this processor - according to a presentation in August 2005 at least 1.25 GHz - but Marvell, which completed the $600 million acquisition of the Xscale processor business earlier this month, believes that there is simply no need for that kind of processing power in handheld devices today. For now and the near future, 624 MHz and perhaps 806 MHz in some high-end devices will be it.

In fact, other processor features may be much more important to help the chip to become more successful than its predecessor. Marvell claims that Monahans has made quite some progress in the areas of Multimedia capabilities, mobile Internet performance and battery consumption. Perhaps most significantly, the chip is able to run H.264 video, encoded at 3 Mb/s, at 30 frames per second and a resolution of 640 x 480 pixels (VGA). Other new features include the support of up to 5 megapixel digital cameras and, according to Marvell, and "hourglass free" web experience, which promises load webpages up to 50% faster than Hermon.


As its predecessor, Monahans is also capable of adjusting its clock speed between 104 MHz, 208 MHz, 416 MHz and 624 MHz, but apparently has received better fine-tuning in using the different clock speeds for specific applications: For example, playing MP3 files only requires 104 MHz, while loading webpages is accelerated at 624 MHz. All Monahans versions include Intel's Wireless MMX2 instruction set, but - similar to desktop and notebook processors - will differ on features such as cache. For example, only the PXA320 will integrate 256 KB L2 cache. Just like its predecessors, the third-generation Xscale processor is still based on a core that is based on 90 nm ARM technology.

here is a better link: http://linuxdevices.com/news/NS8290441804.html

apparenttly is bassed of the arm11 chipset which i dought as they mention iwmmxt2 where as most arm11's have a vfp already.

it seems to indicate a vedeo decoding unit inbuilt (simmilar to the imx.3) however it might be that they got confused with the iwmmxt instructions

will try and get my hands on the manual of this thing
