Protože né každý čte AROS stránky, tak to dávám sem. Je to dnešní info od Gunnara...
Hi
Some of you know me already.
Most people know that me and my friends have developed some new 68K CPU cores.
We are right now working on 68K CPU upgrades for existing AMIGA systems, and that we also work on new standalone 68K System both with original Chipset and also with RGB GFX modes.
I believe that AROS will be the ideal OS for these systems.
Therefore I would like to give you a quick heads up of what new 68K systems are currently available and which are in the pipe.
Right there is relative inexpensive FPGA based CPU acceletors called Vampire available for classic AMIGAs.
These Vampire-FPGA accelerators cost about 90€
offer 64 MB fastmem and have a FPGA big enough
to instatiate our Phoenix 68K CPU in a version
which as of today about has
* 4K Icache
* 4K DCache
* reaches about 80 DMips
Phoenix is Super-Scaler but because of Vampire FPGA size limits the 2nd pipe is not really activated on Vampire. It might be possible to size tune a little and enable at least some instructions on the 2nd pipe - maybe somewhat like the Coldfire V4e does it.
This should bring the Core to about 100 DMips then...
In some test me measured a memcopy speed of over 200 MB/sec on the Vampire already.
Right now in testing are our 2nd generation CPU cards.
These cards are also FPGA based and provide the following features.
* 128 MB memory
* network NIC
* Truecolor video out with 720p resolution support
* FPGA big enough to instantiate a stronger CPU compile.
CPU features in this card are:
* 32K ICache
* 32K DCache
* first target 200 DMips.
A memcopy speed of about 400 MB/sec.
For the next year we plan:
* Working on a "turbo-mode" version of the Phoenix-core which will allow to run faster on the 2nd card.
* Want to bring out an affortable stand alone systems based on the above CPU cores plus our version of Amiga chipset.
While these 68K systems are of course not as CPU powerful as todays x86 systems they should be fast enough to run AROS properly.
The above mentione systems allow running the original AMIGA games, and old applications but at the same time should be useable to AROS on them in a good way.
5 years of development we put the CPU and FPU cores so far.
The whole development was started as part of the NATAMI project. The Phoenix CPU core is very polished now and shares internally many features of today modern CPU cores.
We have some form of simply blog where we post updates on the bringup of the 2 FPGA cards:
If some people like the idea to improve AROS on 68K.
Or if people like to work with some faster 68K syssems
I would like to offer them our support.
I can assist with providing/adding helping CPU features if needed. Or in other topic like e.g. GXF core integration.
Cheers
Gunnar
