That's a stupid attitude if you don't mind me saying so, you don't make progress in one area by sitting on your #### waiting for someone else to make progress in another.

True.
These kind of projects helped the success of the Classic Amiga.
From accelerator boards to the video toaster.
The Xena on the X1000 could help with a revival of custom projects.

sorry but disagree completely with your point of view...
AmifaOS4.x lacks OpenCL/OpenGL support and maybe usb2 wasnt perfect, but that wasnt the real problem...

We NEED RAW POWER!

ALso if you have RadeonHD cards supported fully to play FullHD videos wih low cpu power, also if you have full 3D acceleration throutght OpenGL 4/5/6 or what you like, without RAW power you have no chache to do anything...

Try to render something with blender...
Try to encode videos
try to use some cpu demanding app...

And monalisa project seems to hlp us in that...and also at low price...

It can be used to compress raw full HD video stream to H.264 format (for example). Other formats are supported but TI drivers are quite crashy...

To exploit this chip you have to buy developer kit from TI and their Code Composting Studio 4 is the crappiest IDE in the world...

Other than that it is yet another gem from TI.

Please note this chip won't give OpenGL support to OS4. TI offers OpenGL implementation but all graphics must go through this chip. The chip could be used as USB/ethernet "coprocessor" but it wouldn't offload any work from the main PPC CPU.

For video encoding this chip is very useful. You happen to have full HD camera at home outputting raw data?

Don't forget you can have 3 full HD stream. You can also record video and apply real time effects on video.

yes..but now, you have to say what software there are on AmigaOS 4 to use any monalisa features?

@Seiya

It wouldn't make sense to develope software just in case a particular piece of hardware became available. The hardware needs to come first.

@AmigaBlitter

There are three video engines on that chip but you need more HW to get that video in and out.

AV IN/OUT are included in the selected board.

I see. Then it could be powerful board to process full HD video stream in real time. ARM core is not very powerful (despite being clocked at 1GHz+) but on DSP side one could run simple machine vision algorithms. Developer support from TI is excellent and you can run both Linux and DSP/BIOS (simple RTOS from TI) on this chip.

mm. i dont understand the purpose of this. it has not only relate on drivers but also software has to be exeptionally programmed to make use of it, am i right? if so, then it is best case another track leading to nowhere. for raw power an accelerator should be transparent for the system like 68k accels were. the p5 ppc approach with its necessity of dedicated software was a pure mistake regarding its complexity, therefrom resulting price along with poor applications library.

@itix

Arm core is clocked @ 1,2 Ghz (about 2.200 MIPS or lower). The DSP is programmable and can very very intensive AV calculations. The 3 video coprocessor have their own engine to capture video stream.

There is still hell lot of data for DSP to process if you are using full HD video source at 60 FPS. It is only 16.7 milliseconds per frame. Especially if you want include colour information.

Lowering resolution of course helps and when using VGA camera (640x480) or analog camera (720x288) you can build lot more real time applications for it. The DSP is programmable (obviously) and its instruction set is actually like any desktop CPU but just includes special instructions and techniques to boost algorithms. Nothing special there, really. It can be programmed using C/C++ and you have full access to all special features in C language using compiler extensions.

We benchmarked that ARM core for GBit ethernet performance and results were only mediocre. Maybe TI drivers were just slow or something but apparently ARM core is not optimized for performance but low power consumption. Not bad for this chip though. Typically DSP would be used for video data processing and ARM core is used to master ethernet, USB, PCIe, video engines and so on.

"accelerators killed the amiga by saturating the userbase."

Sounds pretty weird and totally wrong.
Care to elaborate?

IMHO, accelerators made Amiga superior in many ways.

but only for those who could afford them. accelerators, as we all know, were third part trade off hardware patches for what commodore did wrong from the start, ie not consequently introducing improved hardware at affordable price. who would need accelerators in a pc world? even on ppc mac there was little necessity for such stuff. we shouldnt make virtues out of desperate measures (even from commodore decline era).

On PC, you don't need accelerators, you just need to change your video card every year and yopur CPU every 2 years. When reaching 4 years, you have to change the whole motherboard.

And on Mac PPC, accelerators were huge success by the way

cpu slot in A3000/A4000 was a great idea. You could increase performance without investing a lot of money in a new one. Having cpu slot in A3000 didn't stop commodore from releasing A3000T, A4000&A4000T. It was an advantage as it made easier upgrading, just like having a cpu socket on a PC board allows you to increase performance inserting a new cpu.

Example: Many years ago I had a pc with an Asus p5a motherboard with a pentium 100, then a p200mmx, then an AMD K6-2 550. The possibility of using a faster cpu in the same board was bad? NO, it wasn't.

You bought an A3000 with a 16Mhz 030 and later you could add a 040/40 for example. Was it bad? no, because it didn't stop cbm releasing newer machines.

cpu accelerators make more sense on higher end models, but on low end models being able to use faster cpus was useful too and allowed us to continue using Amigas many years later.

Putting your A1200 in a tower with hundreds of cards hanging from it isn't very clean IMHO but it was the only solution for some people. Escom planned to make newer models, just like cbm. Claiming that the availability of a cpu slot prevented releasing newer models is ridiculous.

Commodore did many things wrong but adding a cpu slot was a brilliant idea.
