Perhaps they could implement in hardware some usual functions used in multimedia codecs like jpeg, mpg, mp3 h264 or perhaps make some kind of DSP like coprocessor. New software is unlikely to be written but if they created some stuff like a jpeg datatype it would be instantly used by a lot of software. An mpega compatible library would be useful too and for video they may modify AMP2 as it's opensource and could be recompiled easily.

Look up the 'Robin' core on the NATAMI forum... |

If they used Cosmo's graphics.library, it would be very slow due to lack of blitter support. The new blitter is supposed to be 100 times faster than the AGA blitter. |

I said "take as a base" because Cosmos has identified the key functions and that will make easier adding specific Natami functions, that's why I didn't wrote "using Cosmos library is the best thing in the world and will offer excellent performance without any changes". Did I claim that? No, I didn't.
Support for new chunkymodes/screenmodes has to be written and starting from Cosmos work is better than starting from scratch.
Anyway, even if they used Cosmos graphics.library directly it would never be "very slow" because 060+DDR2 is way faster than standard blitter. So you should add that you think all Amigas are very slow.
Cosmo's library abstracts Blitter support from graphics.library so now it's possible to write optimized functions for "natami blitter" if it's found. That has to be done to support new chunky modes, support won't be written magically by a spiritual entity and graphics.library won't recode itself to support chunky, 24bit screenmodes and fast blitter modes.

| Eventually, the '050 cpu will be available on a card that offers superior clockspeed over the '060 (perhaps 133 or 266MHz) but is not superscaler. It will basically be a turbo '030 on speed. Eventually an '070 will be available on a card that is both faster than the '060 and has more modern cpu design... IIRC |
I hate that they have chosen to refer to their super 68060 as a 68070, it always makes me think of the Philips 68070 which was basically a 68000 with extensions for embedded use.

They changed the names to N68050 and N68070 to differentiate between the NatAmi softcore and the failed part numbers that they share the moniker with. |
