Hardware News   Hardware News : Amy design update Part 2

Amy05 update part 2

This is the final update on the Amy05 design prior to BB4 this weekend. Please attend the show and meet with us.

Read more...(mod note)


One of the biggest changes to the Amy05 design from our first released specification is the addition of the .AMD Geode™CS5536 companion device. For Project Prometheus/Amy'05 this becomes Amy’s Southbridge. This is the low cost Southbridge device from AMD that been in many of the newspapers. It’s used in the $100 'One Laptop per child' system, and in many AMD Geode™ embedded designs. It’s a well proven design and AMD continues to refine all the little details to get the most out of the design. Its extremely well supported, and its great to have a working relationship with the AMD people, we take much pride in this.





What’s the Geode™ Southbridge mean to the Amiga community? Software wise the opening of many new doors, and features. For example, one feature built in is the “USB keyboard”, making USB keyboards easy to install and use.


Hardware wise this device provides the following features to Amy05:
AC97 Codec interface,
A single channel IDE port,
An additional 16C550 UART,
Real time Clock and CMOS RAM
Additional USB 2.0 ports,
PC 82XX legacy timers.

There are additional features to this device but we have only highlighted the features utilized by Amy05.

This is the other component of the Kryptos sound system. It is a low cost high performance solution that will in the future, allow for a lower cost design by fully utilizing the USB and ATA interfaces of this device. Also in future Troika designs, will be able to incorporate, many more hardware features not as yet implemented, into future Amy designs.


The CS5536 interfaces to the TSI107 via the 66 MHz PCI bus interface for maximum performance. The 66 MHz PCI bus connects to the 33 MHz PCI bus using a PLX technology PCI 6150 bridge device. The PCI 6150 makes it easier to connect riser cards to the system without violating PCI bus loading rules, an improvement over previous designs.

A side effect of increasing the system bus to 66 MHz was the need for some glue logic, normally quite boring but it did provide potential for a 'Geekport interface' to be easily added. Now referred to as the Amy Geekport.

The aim of this interface was to put some of the fun back into home computing. For too long now if you wanted to add a custom device to your computer, it was too complicated. By providing a simple 8 bit wide interface that connects directly to the PPC local bus it is once again possible to create homebrew devices and connect them to your computer, just like in the good old 8-bit days.

The interface is memory mapped, provides a basic I/O port, can generate interrupts and provides user defined I/O. Application notes and sample designs will be available at product launch.


As a final note, the planned board for display at the show will be a 'developer' prototype. She’s rough around the edges, and we have had “issues” with making our logos look great like we wished. This is the first release which will be made in a limited quantity for hardware testing/OS4 development. There will be bugs to iron out and some improvements will be made, when this process is complete, the necessary changes will be added into the consumer version, which will then be released.

This is the reason we ask for some feedback on the design, there are limited opportunities for changes to the final design. Rest-assured, we will not be making any drastic changes to the system.

Clearification.
As far as I understand it hyperion's contract with A.inc does not allow for them to develop versions >4.0
Anyway, as saimo said, why bother with this right now?

edit: as I am writing this, i suddenly remember that rogue has answered this but cannot remember what he said.

edit2: spelling

This'll be perfect as an MP3 playing, IRC/surf box. The latter mostly while using Linux admittedly (to begin with), but hey, you've got to start somewhere.

Low power/noise computing ftw!

And the Geekport does tickle my fancy, I'm really looking forward for a finaliced price (and the Geekport documentation).

@Insanity

Or maybe they just keep releasing updates for it and just call it 4.0

Depending on the final cost it may be interesting to hook up a half dozen Amy05s and try some parallel computing projects et al. AmiBeowulf anyone? (just kidding.. sorta)

The important thing is this is a start. Hopefully the start of many more OS4 projects to come.

Niiice! I like the geekport idea. Suggestion: route the audio in/out signals from the built-in sound to it, modern sound cards have some pretty good ADCs in them. Too bad you can't do the same with video...

The only thing left now is price, which I imagine will be revealed this weekend.

Hey Hyperion, get busy and buy one of those things so you can get with the portin'!

I think they get a few for free
or as part of the 20 000 Euro port fee agreement

On second thoughts, this may interfere with the funky automagic speaker detection logic in the audio chip...

Hmm. One IDE port is a serious limitation. I hope a future revision will have a SATA controller or at least additional IDE ports.

The board also contains an SIL0680 - so that provides IDE etc.. the geode also supplies another IDE..

So you got two ports - two channels on each.

You could have up to 4 things

This is wonderful! Maybe we will finally have some hardware for the public to run OS4 on. Great updates, thanks!

Thanks for your direct and honest update. Much appreciated.
I eagerly await update part 2.

@Troika

Sorry but I have to ask one thing about the Amy..

The "south bridge" has one channel IDE which I suppose is for DVD/CD-ROM and/or
burners. So my question is.. Is Sil680 still the chip used for harddrives or have you
made a upgrade to SATA in the final revision? If so, how many channels? I guess 2
but 4 would also be nice.

[Helgis mode on]

Will it be possible to overclock the 800MHz 750GL to 1GHz?

[Helgis mode off]
