Get your degree and you should then be in a positio to know if I understand this stuff or not.

Edit: Another thing BTW Deatmeat got wrong. The PS3 does not use all the cell processors in parellel in order to process the AVC codec. This kind of processing is serial, and doesn't lend itself well to parallel asynchronous processing (to put it mildly).

SO I guess you never heard of a term called pipelining.

In fact I have, and the concept is very important for RISC based processors, particularly useful in the communications industry. And I even know about superscaling, code reordering and predictive branching, and how tricky it is to write compilers that take advantage of RISC's pipeline architecture effectively, especially when timing is critical.

However, multi-processing across 2 or more CPUs is a completely different subject.

G4 is reporting that M$ is releasing a Blu-Ray add-on, not an new console with a Blu-Ray drive.

I was talking in terms of software development.

What you would do to develop a multithreaded app is to basically decompose the decoder into a set of non-dependent function modules, then connect each module with FIFO(One module's output would be another module's input). Then assign a thread to each module and you got your multithreading app. This is the easiest way to write a multithreaded app. You can do better than this, but having more than one thread traversing over same data set gets really really ugly.

H.264 decoder on PS3 is in fact broken into three modules each running on an APU, with the final CABAC done on RSX via shader.

That consumes 3 out of 5 APUs available(A dirty PS3 secret that SCEI won't tell general public) to user application. Remaining 1 APU handles audio, and I don't know what SCEI does with last remaining APU.

Probably not enough R&D to finish the product properly. You know Deadmeat, it makes me wonder why Sony went over the top in the PS3 and doesn't even know how to use the full potential of what is actually there. Or is it B that they developed something they had no idea what they were doing. I have a feeling their engineers had no idea what they were doing.

Microsoft issued an official denial for the 1 millionth time.

(also posted to another thread) - relevant here



Hey everyone... just what if Nintendo decides to add a Blu-ray drive to a future generation of the Wii game system...? It's a possibility, right? Then what would Microsoft do to counter - ALSO add a Blu drive too??

Think about it. If (and when ) Blu-ray becomes a popular success in the marketplace (players, recorders etc), even maybe one day as popular as DVD(?), it will put pressure for competitors to add it's HD quality to their own systems (now that HD-DVD is dead), and by then I would think it would be a no-brainer to adopt Blu-ray tech into the body of the various game systems (or the add-on option).

Remember, we are now in the (growing) first stage of HIGH-DEFINITION (TV, disc, etc), and Blu-ray can only get more popular in use.


Above image - Mitsubishi and Pioneer has announced that they have been working on the development of a new Blu-Ray disc (cheaper to produce) using a new technique similar to the one used for DVD-R and CD-R. Well, we can expect to have more affordable Blu-ray discs in the near future.

Lestat or Deadmeat or HDNow or whoever you are, quit making things up and pretending to know what you`re talking about. I got into HDL when you were probably still in diapers.

You mention terms like `pipelining` when you obviously have no idea what the term refers to. And there is no such thing as DVD 2.0 either. HD DVD is dead now, and you`ll just have to stop pretending that it`s ever going to make a comeback in any shape or form.

Here, as a `high-level` kind of guy... perhaps this link is the only one you need to understand and finally accept your situation: http://hddvd.highdefdigest.com/releasedates.html

I`m sorry I had to resort to that, but you`re going to have to accept it sooner or later. Buy a Blu-ray player... and you`ll feel much better.

You mean the same Nintendo that won't enable DVD playback on Wii to save $15 royalty?

Zero possibility based on history.

All download future.

Pipelining refers to the practice of placing latches controlled by control unit along the processor execution path in between stages, to enable quicker signal synchronization and enable higher clockspeed.

Why don't you ask that question to DVD Forum WG-12?

Why waste my hard earned money on something that will die out in a couple of years?

Deadmeat... thanks for your opinions, but I'm not convinced.

When someone suggested that you purchase a Blu-ray device", you responded - "Why waste my hard earned money on something that will die out in a couple of years?" So, now your predicting the demise of Blu-ray in a couple of years? (oh boy... shakes head)

Counter this with the previous reports that Nintendo is likely to include a DVD drive in the Wii this year, but apparently you'll have none of this possibility, as you said - "the same Nintendo that won't enable DVD playback on Wii to save $15 royalty?"

Well, I've heard different (although the company has not yet made a definite confirmation/announcement) - reported late last year (INFO) - It looks like a recent posting on Nintendo’s Japanese website referring to Wii DVD playback is 100% kosher and not some kind of cruel hoax…

According to a Q&A on the site the new functionality will be added in 2008. Turns out it was originally due in the latter half of this year too, but it had been postponed while Nintendo struggles to satisfy the ongoing gargantuan demand for Wii this year. Fair enough, we suppose. Anyway it’s not yet clear whether DVD playback will work via some kind of firmware update or will only be available for a new generation of consoles. Fingers crossed it’s the former.

So that’s a piece of good news in the pipeline, right? Okay DVD is not quite the equivalent of HD DVD or Blu-Ray, but for those of us without the visual acuity of a Kestrel or the bank balance of a city trader it’ll do very nicely for the time being, thanks. We wonder what other surprises Nintendo has got up its sleeve…?

Further... I suggested that Nintendo might add a Blu-ray drive sometime in the future, as the popularity of HD games increases, but you don't think so, and responded with "Zero possibility based on history."

But I'm talking about the FUTURE... to the day when Blu-ray's growth and adoption is much greater than it is now, which many analysts expect over the next 5 years. There's no other disc technology in HD that offers greater quality and potential than Blu-ray, and it shouldn't be much further in the future that a 200GB Blu-ray disc is ready for production (and probably affordable).

Microsoft vs Sony aside, the Wii is not currently a hi-def device, but could eventually add a Blu-ray drive for future development of Wii-HD games?... possible.
