News   News : AmigaOS 4.0 Status Report
   posted by Mikey_C on 8-Jun-2004 22:34:48 (44659 reads)
By Hans-Jrg Frieden, Hyperion Entertainment

With the Developer Pre-release finally out, the time is right for a status report on the current state of AmigaOS 4.0. The huge amount of work invested into the project by a lot of dedicated developers means that there has already been substantial progress since the pre-release.


Some of the 68k components of the pre-release have in the meantime been ported to PowerPC code. The most prominent of these are Picasso96 and MUI. While Picasso96 is still in alpha test among the developers, the PPC version of MUI is being beta-tested right now, and is expected to be stabilized soon.

The kernel has also seen some updates. Among other things, it now supports a special resource called the performance monitor. The performance monitor is a hardware profiler within the CPU that allows the programmer extremely fine-tuned profiling of code, even including counting cache hits and misses,instruction timing, pipeline stalls, number of instructions patched, instruction throughput, and a lot of other factors. The performance monitor is controlled via performancemonitor.resource, which offers an easy-to-use API that wraps all this functionality into a few functions.

Further improvements of the kernel include support for the Altivec unit. The Altivec unit is a SIMD vector processing unit. SIMD stands for "single instruction multiple data", meaning that a series of instructions is executed in parallel on multiple streams of data items. Altivec has a lot of uses, most prominently in 3D graphics, but also in image processing, signal processing, compression/decompression, and all general computing applications that inherently work by executing the same instructions on large datasets. Altivec support in the kernel isn't 100% stable yet, but is expected to be fully functional very soon.

Moovid, the well-known media player, has now also been ported to PowerPC, and the results are quite spectacular. An Altivec-enabled version is also in the works. Moovid plays a wide range of movie codecs, including DivX.
A lot of progress has also been made on the shared C library, newlib, and the static C library, clib2.

Subsequently, there is now a new gcc compiler suite that runs up to six times faster than the compiler included in the SDK. Furthermore, since the final release of GNU C 3.4.0 has emerged, it has also been successfully ported to AmigaOS 4.0, and is now used for most components and programs. GCC 3.4.0 features a much better code generator than previous versions, much better support for ANSI C++, and implements the Motorola 'vector' extension for Altivec (meaning you can use types like 'vector unsigned char x' in your program to signify a vector for Altivec).

One program that has seen a tremendous speed boost is AmiPDF. The new PowerPC version of AmiPDF is, depending on input, up to 60 times faster than the original version on the prerelease.

Furthermore we expect a working serial device and floppy support soon.

The USB stack is shaping up as well. It now supports HID devices like keyboards and mice as well as HID joysticks and steering wheels, and USB mass storage devices like USB sticks, flash card readers, 7-in-1 card readers and cameras.

The A1 IDE device now has working UDMA support. Also, interrupts are no longer polled but delivered properly. This means that the device does not require any CPU time for transfers.

Currently, work concentrates on performance optimization. Results look quite good already, and stress tests have shown the device to be 100% reliable - no data corruption occurs

This material will in due course be released for download to registered users of the Developer Pre-release on our web site at:

Yes and MPEG will be supported by Moovid 1.7 for OS4.


Does the Mooviid still look so ugly (like in OS3.9) ?

I pointed Beerman to this report, . . .

. . . and he smiled, saying that he'd definitely have to raise a glass to this progress!

I concur . . . . well done Hyperion folk!

I haven't seen any other os4 Moovid screenshots than those with "ugly" GUI.
Frogger produces more "guru meditations" than Moovid, but at least has rather "normal" gui for these times.

How many years has traditional Moovid gui - 8? It's obvious it should be more up to date now..

I think it's very ugly too, and it just doesn't harmonize with os4 in general.

[complaining as usual ]

Maybe there is the reason why majority of players have separated movie window and control window so controls can be visible even in fullscreen and moved freely
...and no brown please

You know, turning off the brown control panel is just one shell switch, or tooltype...

But tell me why you think Moovid is "the well-known media player


"well-known" means that everybody knows it. From your complaints, you obviously know it, too, so that qualifies for "well-known" in my book.

As for GUI's, well, we all have different tastes...

The things missing/not yet complete in OS4 is just what you (Rogue) mentioned in the status-update? Testing, optimizing mainly, or?


There are other things. I just mentioned things that have seen serious evolution since the pre-release. We're still planning to do some things that I didn't metion.

Quote:
Also, since you didn't mention 68k JIT emulation in your update, what does that mean exactly?


Nothing really. It only means that since the prerelease, it hasn't seen much changes.

I said it looks ugly but not that it is useless...

"well-known"
ahh sorry, english isn't my native.
I thought it should also evoke positive rating... I was wrong. Sorry

But the GUI *IS* ugly no matter what taste you have (IMHO its the problem of AmigaOS, it doesn't look consistent enough since OS3.5)

I did not. Really. Only what I heard recently. That it plays movies.

But I do know moovid as move your lazy butt of the chair and put the trash out. Or as you did, moovid with that pre-release.

@vortexau

I always enjoy it when Beerman comes to pay me a visit. He does not say much at all. But then again, what's the point of that? We talk to the wife and drink with our famous buddy! And the last rather then the first.

It was known as "Action" under OS 3.9.

Many thanks for taking time out to give us such a detailed update. The progress looks very good , congratulations are in order to Hans-Jrg and the Hyperion-OS3 team

Question: Any "guestimate" ETA for the scsi.device, I have burner & ZipDrive ready to give it a test drive!

Regards,
JCC

Sorry, again. But I never had OS 3.9. Always just standard Amiga's. I did not belong to the "upgrade" people. Always wanted too but there was always something new just around the corner so I waited. But this way my view on OS4 will be a fresh look. Really looking forward to the SDK.

"When its done"
Honestly, I can't tell you for sure, I don't work on that (and even if I did...). AFAIK it works quite well but is lacking support for modem signals.

Can't say fairer than that! Oh well, added incentive to get broadband then!!

Hi,

Just found out that my dealer got the cd's today (wednesday) and they are going to be shipped also today. By now mine is on it's way. With luck next wednesday and if no luck longer or even longer then longer. But if I do get it then next week I have to go away for some days too. The important thing is that I have it.

Good news for you. However, there's still not even a word from the UK sides
