Intel PXA250 XScale Processor
http://developer.intel.com/design/pca/prodbref/298620.htm
Intel has released some detailed specs on the Xscale CPU - this is one bad mother of a CPU. ;-)
� Low power, high performance 32-bit Intel� XScale� core-based CPU (200, 300 and 400 MHz)
� ARM** Architecture v.5TE compliant and application code compatible with Intel� SA-1110 processor for rapid upgrade
� Intel� Superpipelined RISC technology utilizing advanced Intel 0.18� process for high core speeds at low power
� Intel� Media Processing Technology including 40-bit accumulator and 16-bit SIMD to enhance audio/video decode performance
� Low Power and Turbo modes for optimal battery life
� 32 KB data and 32 KB instruction caches
� 2 KB mini data cache for streaming data
"...Integrated Memory and PCMCIA/CompactFlash Controller with 100 MHz Memory Bus, 16-bit or 32-bit ROM/Flash/SRAM six banks, 16-bit or 32-bit SDRAM, SMROM four banks, as well as PCMCIA and CompactFlash for added functionality and expandability..."
"...Peripheral Control Module offers 16-channel configurable DMA controller, integrated LCD controller with unique DMA for fast color screen support, Bluetooth* I/F, serial ports (IrDA, I2C, I2S, AC97, three UARTs, SPI and SSP), USB end point interface, and MMC/ SD Card Support for expandable memory and I/O functionality..."

i'd hope for at least 128 for the rom, at least, and no less than 256 for the ram.
plus, i'd want thinner/lighter too, better button placement, a kickass screen, built-in bluetooth, etc!
and for the iPaq - a BACKUP battery!!
oh yes, under a grand (and the further under the better)!!!

You probably need a docking station with huge hard drive, and a keyboard too. :lol:

Ah, as long as we're fantasizing, why no .15 micron process? And hey, where's my OLED screen, hmmm?
Anyways, I wonder what new capabilities the 400MHz PXA250 will enable? I just read somewhere where someone was saying that 150MHz XScale would be similar in speed to 175MHz StrongARM, also that the 400MHz PXA250 can take as much as 30% less power than the 206MHz SA-1110...? Not sure if they're factoring XScale's SIMD into the speed comparison...
How much better will we be able to play MPEG4/WMV? I think full-rate VideoCD MPEG1 will be achievable. Continuous speech recognition, that'd be so cool (but please include much better quality microphone!). Also I hope all the PPC speech/multimedia software developers are already hard at work incorporating XScale SIMD support...

USB 1.1 built in
The White Paper (same page) is a fascinating read.
Probably most important of all is that USB 1.1 is built into the processor. Thus two devices, or a device and a PC, can sync using a standard cable; I hope all this'll finally fix PPC synchronisation problems ...

So no direct support for USB-on-the-go (which is the 12mbps peer-to-peer extension to the USB 2.0 standard, which also uses a smaller connector design)?

No, probably because it's too new (I guess the lead time for a processor is easily 18 months or 2 years) ...

benchmarking?
Is there any kind of benchmarking software for the PPC? I'd love to see how it stacks up against my various desktop PCs

From all I have heard, and from this information, It appears that the XScale is going to be one killer processor. All I've got to say to that is- COOL! 8)
