Has the internet banned hotlinking nowadays?

You can certainly post attachments; go into advanced when making a post, and then go to manage attachments. You can there see what filetypes/sizes are possible. But hotlinking is definitely a simple approach, as long as the documents are readily accessible.

if the documents are NOT readily accessible then think VERY carefully about posting them.

If they are proprietary or confidential and have leaked somewhere then do not post them, no matter how good you think they are.

Hotlinking is the simple solution since that is deffo "on the web" and not just found in some torrent somewhere.

Yes, you are right. I've read only 35XX TRM before and there is only 'video accelerator' box in IVA 2.2 subsystem fuctional description and nothing else but 34XX TRM indeed has whole 'Video sequencer' chapter which is completely missing in 35xx TRM. This sequencer is indeed ARM core which can control accelerators (filtering and motion estimation) just like the dsp can. I wonder whether 35XX has it too or not.

I think that OMAP2420 is composed BY :

ARM11 - C55x - IVA (or ARM7)

you can use ARM7 to do elaboration with C55x and in the same time ARM11 can elaborate other process...

Is it correct ??? We need to undestrand how program ARM7

Differences between IVA1.0 and IVA2.0 is :

-------- -------- ----------
| | | | | ARM7 |
| CPU | | DSP | | IVA1.0 |
|_____ | |_____ | |_______|
|__________|_______________|


-------- --------------
| | | IVA 2.0 |
| CPU | | ARM9+C64x |
|_____ | |_____ _____ |
|_____________|

In the first time we have 2 system with the same bus (IVA1)
in the second we have 1 system with internal bus and external CPU can
work without confict.

I love ascii

Code:
      --------      --------  ----------
      |         |     |         |  | ARM7   |
      | CPU   |     | DSP   |  | IVA1.0 |
      |_____ |     |_____ |  |_______|
           |__________|_________|


      --------     --------------
      |         |    |    IVA 2.0    |
      | CPU   |    | ARM9+C64x |
      |_____ |    |_____ _____ |
