SAM460 owners - ArcEm OCM benchmarking - please help

Hello!

I've produced an on-chip memory optimised version of ArcEm. It puts emulated processor registers and various other bits of state information into fast OCM, instead of main RAM.

However, I don't own a SAM460, so I can't test it.

I'm looking for some benchmarks done with each version to check it makes a difference, and to see how much. This might have implications in the future as to whether emulator authors/porters put registers into OCM. I'm hoping this is going to make a noticeable difference, but we'll find out!

You will need:
onchipmem.resource
ArcEm full installation package
ArcEm OCM binary + !SICK (NB: UPDATED 28/02 20:10 GMT)

1. Install onchipmem.resource if you haven't already
2. Install the full ArcEm package (don't rely on anything you have installed being the correct version)
3. You'll need the RISC OS ROMs too. Scroll to the "alternate sources" section of this page
4. Install ArcEm OCM in the same place you installed ArcEm.
5. Run ArcEm_OCM. In HostFS you should find !SICK. Run this and save the results file somewhere when it is done.
(btw, the easiest way to quit ArcEm is to press F12 and type arcem_shutdown)
6. Edit ArcEm_OCM's tooltypes to enable the DISABLEOCM tooltype. (NEW)
7. Run ArcEm_OCM. Run !SICK. Save the results file somewhere.

Paste the two results files here. The "Clock rate" should be the most important bit of data.

Thanks for helping!

Chris, I can't download the ArcEm OCM binary. File seems missing.

Wow, that was fast to provide an ocm enabled program!

But the result is the other way around. First the ocm version, then the standard one:

< Clock rate: 3.0620 MHz
> Clock rate: 23.787 MHz
< High ROM access time: 325 ns
> High ROM access time: 450 ns
< Memory clock: 10.70 MHz (reported by > Memory clock: 65.27 MHz (reported by OS)

It's easy to do - it's just memory allocation using a different function.

Hmm, that's not right.

Did it feel as if it was running that slow? It might just be misreporting.

OK, until somebody tells me it is crawling along (which they haven't yet), I'm going to assume !SICK is misreporting.

Attached is !ARMsi. I'm not sure if it reports correctly on ArcEm, but I'm getting about 8.3 MIPS here and it is changing every time I recalculate, so I think it might be.

It can be extracted straight into HostFS from the Amiga side.

Perhaps we'll get some more sensible results with this.

Chris,

Regarding your comment, We should have reported (well at least in my case) that the OCM version is slower than the regular one.

I will test the !ARMsi on the Sam tonight.

Curiouser and curiouser.

sofistisoftware is getting the results I would expect - a ~1Mhz increase in emulated CPU clock speed, and big gains for cache memory too.

davebraco and Elwood are getting speeds reported to be 10x slower.

So, what we need to figure out is, what's different between sofistisoftware's SAM, and davebraco/Elwood's.

These might help:
OS version + update status
Exact model/spec of SAM460
Additional hardware/non-standard software running at boot
Is it a SAM460 or an AmigaOne500 branded? Motherboard revision?
Anything else you can think of

Oh, and if you can re-run the OCM test again and see if you still get the same result, that'll be useful.

Yes I can confirm ArcEm_OCM is x10 slower on my SAM460. Running both emul-versions from RAM:

I bought only the SAM460ex mb and assembled myself.

The output from the example in the onchipmem archive might be useful to compare too.

Just in case there's other factors at play, I've updated the version of ArcEm in the OCM archive. It now has a DISABLEOCM tooltype, which will cause it to run without using OCM. I'd be interested to know if that produces the 10x slower speeds too.

Well,

what we can really figure out, is that you need a 460 too :)

Maybe a bounty setup for chris?

Being serious, you was really fast to test the new feature provided by Acube. I'm impressed.

Well done dude.

@Chris

I'm not sure I understood what you wanted us to test.
Running the updated program (with its DISABLEOCM tooltype disabled as in the supplied icon) it is still slow. Clockrate at 2.91

Davebraco and I are betatesters so we are using up-to-date systems.


Sam460 and AmigaOne 500 should be considered the same. I have 2GB RAM. I'm pretty sure Davebraco too.


ARMSI gives 2.04 Mips with the ocm version.


Now I can't run the standard version :-/ Tried twice and It opened a black screen and then stopped. Now I downloaded again the archive (link you gave) and I always have a crash:
Crashed process: ArcEm (0x4B8B2530)
...
Stack Backtrace:

Hmm, I think we're onto something here. Everybody who has reported the OCM version being 10x slower are OS4 betatesters, right?
The only people so far to have reported a speed increase are sofistisoftware and klapdeur, who aren't?

Looks like a bug or change in the OS4 beta is causing this problem.

Can we get some stats from the example program in the onchipmem.resource archive? If that is also running slow on beta systems then there's a problem with OS4 beta for sure.

I'm not sure I understood what you wanted us to test.
Running the updated program (with its DISABLEOCM tooltype disabled as in the supplied icon) it is still slow. Clockrate at 2.91


How about with DISABLEOCM enabled? (it should be back to normal speed - but I want to make sure it's OCM usage causing the problem)

(btw, the crash is usually because it can't find the ROM, there's a bug in the previous release which causes it to crash instead of reporting errors)

@Chris

is ArcEm using CopyMemQuick by any chance ? Or is it using CopyMem / CopyMemQuick on OCM memory ?

@m3x

No, there's only one instance of CopyMem and that's something to do with bitmaps (nothing to do with what I've put in OCM). I checked the entire source for memcpy too and found four instances, three of them related to loading files off disk (so not relevant) and the fourth was something to do with screen updates (and didn't seem to be touching what I'd put in OCM).

edit Hmm, could it be alignment related? I'm putting a structure into OCM, and then poking individual values, but it's all on default alignment (whatever that happens to be).

Chris,

I run it under update 6 and got the same results.

Here is the output of ocm_test :
