It is an RISC architecture and currently I only know, that it has a MMU
and is 32 Bit.  Afaik is the MMU neccesary because the 64 MByte internal
memory can increased with external ones (I think it is up to 256 Mbyte)

The chip is a so called "Singel-Chip-Computer with OS-On-Chip".

I have found several Manufacturers for such chips while I was looking for
an ultra-Compact-Version of a Mainboard/SBC.  Most of them are based in
ia32.  But the Manufacturer of this new architecture claim, it is MUCH 
faster as all equivalend ia32/arm/mips based CPU's.

Since two other peoples have send me some Links to porting-docu
I have not to read all the stuff...

Note:  Currently I am poking arround with a Ultra-High-Speed
       DSP for realtime analysis of Radar-Signals.
