X5000 + Sapphire Radeon RX580 Nitro+ 8GB

Works like a charm and is much faster then a RX560.

It's not really loud. At least I can hardly hear it when my tower is closed. Have it always on high power.

@amiganuts

AmigaOS, every variant, can only address 2GB. So this is normal. There's extended memory bu means of bank switching. But that is hardly used.

The reason to use such large memory is that it is dual rank memory. This gives a some bandwidth benefit over single rank.

@hitchhikr

Hi and welcome.

You are the developer behind Protrekkr, right?

Nice work!

Here's a small memory test tool which compares cache and ddr bandwidth for both normal transfers and cache hint "optimised" transfers. For now only dcba and dcbz are used. These instructions are supported by at least the e5500 and ppc440 cores.

The implementation is very basic and there's room for optimisation.

I will also try to implement dcbt dcbtst in a future update.

Nice program. Thanks for the port. I can confirm that the gui is the cpu hog. Everything runs fine unless I enlarge the window to show show all 16 tracks. Then even the X5000 will reach 100% cpu load. So maybe we should try to get rid of SDL and make the gui os4 native.

Merry christmas everybody. Let's wish for a multicore new year

@kas1e

I've noticed a small issue. Haven't read the chat so maybe it has been mentioned before.

Wb2filer doesn't work correctly for Usb media with space in its name. For example when I try to open a USB msd with "No name" as volume name then I get a popup asking me to insert volume "No:"

Maybe some can also answer me a question about filer itself. What is the purpose of the SOURCE and DESTINATION. How do you use it as source or destination?

@nbache

Just fitting the card doesn't make my amiga a musical instrument. Only when I install software which allows me to compose music with it does.

But I think the intention of this warning is that Roland will not allow it if the soundfont is used create a cheap commercial GS Synthesizers, GS electronic keyboards etc.

The card also ships with a second soundfont which is not subject to the Roland IP restrictions. The manufacturer offers PC software which allows you to install your own soundfont on the remaining 48MB flash.

However I do not have the musical skills anyways, so I am not worried at all for Roland lawyers showing up at my doorstep.

As far as I understand, there's a CAMD.library usb driver for amigaOS4. So this means that you should already be able to connect that card to our next gen amigas. You could loopback the headphone output to a line in. That webshop sells external cases as well.

Edit1:

The DreamBlaster-X16GS offers even 1 GB for up to 8 soundfont banks.

@Raziel

I have no intention to create something commercial or open source.

The interface is completely different from what is available on your X1000 so what I am creating is X5000 exclusive anyways.

The A1222 doesn't have a xorro slot and the XMOS XS1 is EOL. If a future next gen amiga will happen and still have a xorro slot, the xmos binary and probably the interface won't be compatible anyways.

Yet, xena offers a "low cost" way to expand the X5000 with custom homemade solutions since it circumvents the PCIe interface and includes a 1000MIPS cpu.

Therefore it would be nice if future A1s would at least offer a (buffered) LBC interface.

Anyways, I've already learned a lot about the features and limitations of the xena interface and XMOS chip. Unfortunately, I have to work around some shortcomings as a result of the implementation.

So I am still in the discovery phase.

Next step is to transform my Xenaprobe into a xena device driver which contains the xmos loader and a configurable communication interface.

After that I'm going to port the C64 SID player with a redirect of the synth samples to AHI as a proof of concept.

If all checks out then I'll start a first hardware project.
This will be a high end audio card with
- high quality DACs
- High Quality ADCs
- High quality OPAMPs
- S/PDIF out
- wave blaster interface (I still have the DB50XG, but there are also new tiny gs wave table synthesizers .


The XMOS can do:
- x Band equaliser
- Audio effects
- SRC
- channel upmixing (eg 2.0 -> 5.1)
- Virtual HP surround
- x ch input audio digital mixing
- multichannel -> S/PDIF (a52 encoder)
- Maybe keep the SID player for fun

I order to connect all the DACs ADCs, I'll need a CPLD/small FPGA to provide the I2S interfaces. It would be a waste to use xmos threads for this pupose

This is a YT thread. But since we are off topic:

aiostreams youtube stopped working as well. You can still search for videos but the links don't play.

They do play in YT though.

The Xena interface can manage overall around 10MB/s half duplex at a first attempt.
This is the result of a simple write full (CPU), read empty (xmos) interface.

With a streaming ping-pong buffer, the interface will be able to manage close to 20MB/s half duplex.

Edit1:
~17MByte/s with a pingpong buffer. Not bad.

Edit2:
~20MByte/s after some optimization.

@outlawal2

I think that you need to contact Laurant from AAA technology in Luxembourg.

Merry Xmas. Great to see what still can be done with our little system

@khayoz

Jtag between cpld and xmos works well.

In case of an external debugger, the cpld needs to hi-Z some jtag signals and does buffer TDI as well.

I am afraid that this was never properly tested

If possible, you could try to lower jtag clock speed.

@khayoz

Not exactly sure what you did. This dongle is a xtag debugger which you've connected to your xtag header on de X5000?

And then tried to do some development with xTimeComposer?

If I would not have owned a X5000, I would have bought the A1222 for sure. In the same way that if I would have been able to buy an Amiga 4000 as teenager, I would not have owned an Amiga 1200.

The A1222 is quite capable for everything OS4.

For me, EUR 1000 for the third fastest Amiga ever build sounds like a bargain. Especially when you consider the price of ancient big box Amigas. Even today.

If multicore would ever materialize, it will consolidate its third place even further.

But unfortunately we live in a different world where aliexpress and rpi seems to be the benchmark for anything Amiga that is not 68k based.

@AmigaSociety

Yes, it is a bit cryptic. The thickness of the line to the x4 slot already suggests multiple lanes. Compared to the thin line of the x1 slots.

I know for sure because I use the x4 slot for my Nvme driver and can confirm that indeed 4 lanes are connected. But you can also check out the connector pinouts. There's only a remark for the x16 slot that lanes 4-15 are not connected. There is no such remark for the x4 slot.

@AmigaSociety

If you want to know something technical about your X5000 then you could also check out the X5000 TRM yourself. If you don't have it then you can download it here: https://amigaone.files.wordpress.com/2 ... /trm_cyrus_1-1-1_aeon.pdf

But to answer your questions:

1. The X5000 x16 slot is directly connected to the P50x0 with 4 PCIe2.0 lanes. This means a bandwidth of 2000MB/s

2. The x4 slot is connected with 4 PCIe2.0 lanes to a PCIe switch. Which is in turn connected with 4 PCIe2.0 lanes to the P50x0. So also 2000MB/s. But a bit higher latency due to the switch.

"Just" 2000MB/s is no issue at all. Various tests on PC websites reveal that the difference in fps between PCIe2.0 x4 (2GB/s) and PCIe3.0 x16 (~16GB/s) is just a few %.

Nice vid!

You should also check out your "Power" pref. This preference tool allows you to switch the card between high and low power mode. High Power means more performance.

My setting is saved to High power mode. But for some reason, it fails to apply High power mode after a reboot.
Kas1e came up with a fix by forcing the Power pref to run once after reboot with adding the following line to the the user-startup:


It looks like your power pref is set a low.
I can run the same voxel edges at 120-200 fps in the preview window (vsync disabled). And about 20pfs fullscreen

My personal favourite shader is multipass->Full screen radial blurr. This one runs at ~80fps in full screen mode.
