Good god lets not get started with this Bochs/windows emulation again. Even I started a topic about this subject nearly 6 months ago. Can't we just move on?

Back to lurking.

six months ago we did not have Mike Eggleston's tidbit of info
six months ago we were not 1 month away from a machine that has the horsepower to run bochs.


I'm sure 12 months ago people would have said "good god! internet explorer won can we get over this html rendering thing and just move on?"

Ok, then how bout this. There was a lot of talk and speculation already written about this subject- why don't we resurrect one of those threads instead of rehashing all that same information which to me is somewhat OT to this thread?

Back to lurking for real this time.

as you know, safari is really made up of 2 parts. the cocoa app, windows, menus etc. and the html rendering engine. this engine is actually open source. it was started by the kde group and called khtml. apple took khtml and made is better and gave back their changes to the OS community.

the html rendering portion is called webCore. this allows 3rd party developers to "use" this rendering engine and display html code in their apps. like omniweb is doing with their next rev of their web browser. they are ditching the old rendering engine and using webcore to give them the exact capablities of safari. (plus what ever they add) itunes uses the same for the music store.

if apple did the same with the boch code (winCore?) then 3rd parties could use the winCore and build their own windows emulators.

Oh, was it that simple Just had a cup of coffee myself

Ok, so Apple makes their own emulator. An emulator that is integated in os X much like classic. I suppose Apple would make this emulation faster than anyone else, because of their knowledge of the os and hardware. Why would anyone else bother with this then?

And my previous comment stands. I think it would be very dangerous for Apple to make a seamless windows emulator environment because of the reasons stated before. Of course they can help other companies develop nice emulation environments, and I would rahter see that happen than Apple providing one.

oh i agree with you.

about the only thing i could think of would be to give back to the linux community a _really_ good windows emulator. that's piss off some M$ people.

another reason why would be when apple releases OSX - > Intel in Jan 2004 with a Superbowl - 1984 commerical. they would be prepared for the immediate shelving of the mac version of Office

Really? Does x86-64 (or whatever it is) have enough registers now? I believe that was what was the bottleneck in emulatiing PPC (hence why there are only 68k mulators out there for x86 right now).

Please correct me if I am wrong, but my understanding is that Bochs is a Windows emulator. A Windows emulator and a PC emulator are two entirely different things.

Bochs runs under Unix/Linux on x86 machines to eliminate the need for Windows...but when those Windows apps start talking to the x86 hardware, the hardware is there and ready to listen.

Bochs would be useless (in it's currently publicly available versions, anyway) on a Macintosh PPC based machine because then the Windows apps starts to talk to x86 hardware that is really a PPC, it would choke.

Bochs would need to be turned into a full-fledged PC emulator, like Virtual PC, which means instant hits in performance. Unless Apple is working with Bochs AND designing a Virtual PC replacement of it's own, optimized for OS X, I'm not sure we have anything to talk about.

I tought Bochs ran on PPC already. I may be wrong though.

Edit:

from the Bochs homepage

Quote:
Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, bochs can be compiled to emulate a 386, 486 or Pentium CPU. Bochs is capable of running most Operating Systems inside the emulation including Linux, Windows® 95, DOS, and recently Windows® NT 4. Bochs was written by Kevin Lawton and is currently maintained by this project.
Bochs can be compiled and used in a variety of modes, some which are still in development. The 'typical' use of bochs is to provide complete x86 PC emulation, including the x86 processor, hardware devices, and memory. This allows you to run OS's and software within the emulator on your workstation, much like you have a machine inside of a machine. For instance, let's say your workstation is a Unix/X11 workstation, but you want to run Win'95 applications. Bochs will allow you to run Win 95 and associated software on your Unix/X11 workstation, displaying a window on your workstation, simulating a monitor on a PC.

That's what I've heard as well, and Opteron has only 16 (general purpose) registers compared to 32 for all PPCs.

No, it's a PC emulator. In theory it should be able to run any PC-compatible OS. You may be thinking of VMWare or VirtualPC for Windows, which let PCs run multiple OSes simultaneously, sort of like how OS 9 runs under X.

Bochs would need to be turned into a full-fledged PC emulator, like Virtual PC, which means instant hits in performance.

It already is, and you're right, performance is a major issue.
post #571 of 666
NETROMac ... my apologies. You are correct. I was actually confusing WINE with Bochs, which are two different projects. WINE (again...from what I recall) emulates Windows without emulating the actual x86 platform...which apparently Bochs DOES do.

Programmer, Johnsonwax, Amorph and others.... What do you guys think of this:

Paper in PDF format.


Thoughts? Speculation? An AltiVec implementation?

Perhaps someone should contact the authors and see if they're planning (or are willing to do) an AltiVec implementation.

I read that too. Its possible that bryce was "just" cancelled. But what is looking more and more probable is that macbippyboopy is either receiving or giving false info...

No, Bochs is a PC emulator that emulates an x86 processor and chipset. It does not eliminate the need for Windows for Linux machines.

It's so incredibly slow that it doesn't eliminate the need for anything other than patience. Consider it to be a horribly slow implementation of RealPC/VirtualPC.

VirtualPC is roughly 100x faster than Bochs is. Bochs would hope it became more like VirtualPC

If true, this takes an already large hole in their credibility and widens it some - the benchmarks smelled funny even if you granted them a developmental build of Bryce 6.

And, of course, the recent press release does not mean that there never was a build of Bryce 6 for OS X. Half-LIfe for Mac made it all the way to release candidate before it was axed...

Whether this means that all of their information is bogus is impossible to say, but they've gone pretty far out on a limb, and we'll probably know within weeks if that limb can support them.

Talking about pc emulators. According to SpyMac it looks like FWB's RealPC for Mac OS X is delayed.
Quote:
FWB's Mark Prewitt told Spymac this:

"With the recent updates to 10.2 and the upcoming release of Panther, we have elected to delay the product by a few weeks to better deal with some technical issues that have risen,"
...
"We should be back on track and will be putting some kind of update on our web site shortly."

That's alright. Better to take their time and bring out a good product, then to rush it and have to deal with bugs (other then the big one called Windows).

Speaking of Half-Life, Wouldn't it be great if Steve showed off the mac os X version of Half-Life 2 running on the new 970 powermacs with nvidiaFX running at massive PC-crushing frame-rates.

Well here is my best semi-accurate translation of MacBidoulle's latest.

Rumour: the motherboard of the PPC 970, still - Lionel -
08:47:38

Good, take this all that with more extreme precaution each
time.

The bi-processor motherboard should have in all 8 slots memory. There would be 4 per CPU of them. These sites are ?? and already compatible
with the SIMS of 4 Ghz. One will thus have a maximum memory size of 32 Ghz!! We are unaware of completely how Mac will manage with its RAM. We do not know if each processor will have its memory allocated with possible Twin Bank or if the slots of 4 in fact are paired to make a
Twin Bank between the two.

Subsidiary question: How much will the gigabytes of RAM cost in the ultimate PowerMac 970 with 32.

From the same MacRumors thread that disputes the initial MacDoobie benchmarks; in reference to the mystery ports on the rumoured new main logic board...

Make of it what you will...


FYI - Toslink = Digital Audio connection = SPDIF


I doubt Apple would saddle prosumers with the added cost of Fibre Channel on the main logic board; but I have no problem accepting that they might place Fibre on workstation-class machines...

A lot of hifi/sorround amplifiers can take toslink input, and it would ensure great DA-conversion (if the amp has a great DA converter) and therefore great sound. It would also eliminate electrical noice coming from the computer chip/components. More of a "hi-fi" mac if you know what I mean. It would be a great addition to music proffesionals.
And as toslink is quite commonly used in hi-fi/surround equipement, I would guess that the technology needed for this would be fairly cheap to include.

A more interesting technology (as seen from an Apple point of view) is finally getting implemented in audio systems:

Quote:
The very latest incarnation of the 'AX10' is the new VSA-AX10i-S, featuring Pioneer's revolutionary Advanced Resolution Digital Audio Interface. IEEE1394 - alternatively known as i.LINK or FireWire - is the new industry standard interface for the secure digital transmission of high-resolution audio from DVD-Audio and SACD sources. Pioneer's state-of-the-art universal DVD player features an i.LINK output, while the VSA-AX10i-S now includes a matching i.LINK input for unprecedented fidelity when playing the latest music releases on DVD-Audio and SACD. With sufficient power delivery and transparency to preserve the enormous dynamic range and pure clarity of today's higher resolution digital recordings, the VSA-AX10i-S includes 7.1-channel line inputs and outputs for all requirements.

I'm glad Pioneer's living up to their namesake; FireWire is such an obvious means to simplify and improve the quality of home entertainment systems as whole. I imagine one day just being able to daisychain TV to VCR/DVD-R to receiver to whatever else there is all via FireWire. No cable mess, no confusion.

FireWire does have the bandwidth to support real-time transmission of HD video, right? Or is coax/component/RCA still the only means?

I second that emotion. Although they still refer to it as iLink. (Didn't the standards board agree to switch to "Firewire")?

Cost? $4500. Yowch!

Check out MaGIC (http://magic.gibson.com/)

It sounds cool, but looks to be more for production and performances. But who knows, maybe it will trickle down to the consumer/prosumer markets. I don't want to sound like I know much about it, someone just passed word of it on to me recently.

And yes, it can handle HDTV.

Pioneer isn't a member though, but they seem to be going the same way.
