Microprocessor Forum 85

Posted by michael from the fancy-vacuum-tube dept.
Manufacturers are strutting their stuff at the Microprocessor Forum. Some of the rollouts: Turmoil writes "AMD has demonstrated working SMP. http://www.amd.com/news/prodpr/20165.html" hol writes: "German news site Heise.de reports that a German startup named PACT surprise-announced their processor design at the Microprocessor Forum in San Jose. Apparently this thing is a 128 cpu parallel computing deal which has its roots in the programmable gate array world." infodragon writes "All Linux Devices.com is running a pretty cool article about an X86 chip running on 1 AA battery. They demonstrated it by playing a VCD movie. They also say that mp3s can be decoded/played on it."

  • I seem to remember hearing that AMD used a different SMP scheme than Intel does; a method more akin to how multi-proc Alphas work.

    This article says that 3D Studio Max was used for the demonstration which means NT/2000 to me.

    If dual-proc Thunderbird motherboards were to arrive on the market a month from now, is the code for linux to take advantage already in place?

    Did I just get information when I heard that AMD's SMP is different?

    The world of CPU design has been quite stagnant in recent years. Yes, there have been truly massive improvements in an engineering sense, but architecturally speaking, the latest Pentium and the various 64-bit candidates are really no different to a little ol' Motorola 68000 at heart. Harvard, RISC and superscaler designs haven't departed significantly from the same basic and extremely limited architecture which dates back to three decades ago or more.

    But PACT's XPP is a different thing altogether, a dataflow computing engine on a chip. This thing is so far outside the current norm that it holds exhalted company with only a very few select others: my list of such exceptional architectures would probably comprise the Intel iA432, the Inmos Transputer, the Crusoe, and now the XPP. (I'm only including real candidates for implementation as micros, not research or demonstrator platforms of which there have been many hundreds of great ones.)

    It's beautiful!

    My research work on parallel architectures and concurrent languages really needed hardware like this to blossom. I wish the XPP had appeared then!

    If you need 64-bit processors in your server, you buy Sun SPARC, IBM PPC/64 or DEC Alpha. You spend a lot of money, you get a lot of them in one box, and you don't care about the price, because $5,000,000 for a server (OK, maybe $200,000 at the low end) is trivial.

    The good thing is that the companies that sell these chips support Linux (and other free OS projects). The bad thing is that no sane company will ever run a free OS on a box that costs this much.

    AMD and Intel are both building 64-bit chips. That's nice. Real computers, running real operating systems have had them for years. Until you need >4GB RAM in your cute little desktop peecee, forget about 64-bit processors. One day they will be there for you, and AMD and Intel will be selling them, But the real processors, in the world of the grown-ups, will still be so far ahead that the leet peecee brigade won't be able to comprehend it

    I bought a Micro-ATX Cyrix MediaGX mobo a while back ... And it plays 'The Road Warrior' just fine!

    I note here that the MediaGX chip is not just "yer average CPU", it's a CPU+media operations. It's designed in a similar but broad vein than MMX and SSE. The idea is to allow one chip to be the heart of a el-cheapo media box, such as the mythical "set top box" that will make some hungry MBA a jazillionaire.

    Cyrix created this chip to try and pre-empt-slash-cash in on the "set top" market. The idea was to allow you to use the MediaGX by itself (one chip, cheaper to build and easier to design) versus a "standard" CPU + media copros. Hence the MediaGX has a whole bunch of instructions tuned for sound and video processing.

    When you add the fact that DirectX has native support for MediaGX instructions, you find that it's quite feasible for it to handle a DVD decoding load. I'm not sure that the same could be said, however, of a vanilla Pentium of the same era (without MMX).

    When it comes to single processors, the Athlon and the PIII are pretty much equal on a clock for clock basis (Athlons reach higher speeds).

    But when it comes to SMP, the Athlons should have a BIG advantage; the EV6-protocol.
    The EV6 which is the bus used by the Athlon-arcitechture, and licensed from Compaq (Alpha)
    provides DEDICATED bandwith for each of the CPUs,

It appears from the bits of technical information that I looked over on their web page that you have to program the reconfigurable part of the chip differently from the rest of the chip. What this means is that you can't just take a C program and create a new compiler backend to dump out a program for this beast; or if you can, it will take some SERIOUS work by the compiler people.

    I am currently involved in some research where we are trying to solve the same problem, roughly. However, we are trying to make the change as transparent to users (i.e. compiler writers & assembly code writers) as possible by making small tweaks to the standard RISC concept that will allow our chip to extract large amounts of parallelism. It is clear that with these reconfiguration based architectures it is possible to have huge performance gains at the expense of programming complexity. Hopefully our architecture will be to these reconfigurable systems what superscalar was to VLIW. VLIW has been around for a long time, but it wasn't popularized until architects came up with ways of making a VLIW core look like a scalar processor to the outside world.

    We'll see.

Once they bought all of NexGen's brainpower with the chump change they made from ramping flash (Intel fumbled the flash market in 93-94, which let AMD win some capital $$$), Nexgen all but handed over the k6 and k7.

    So does AMD deserve credit for the K6 and K7?

    Reworded: does a company deserve credit for intellectual property that it purchases?

    Tough call. I would say, yes, they do. It all comes from talented engineers, and whatever faceless company that they're a slave to owns the rights to their intellect. AMD had very little talent in the late 80's-early 90's, then they bought some. The exact same way that Intel is trying to buy dominance in the networking world. Isn't that capitalism?

    In contrast, Xilinx [xilinx.com]'s strides in FPGA and RC technology tend not to feature because there's a gulf between a beautiful RC chip like the 6200 and actually being able to compute with it. Even Xilinx know that now -- their newer devices are more advanced FPGAs but they don't even attempt to carry the generic RC mantle like the 6200 tried to do, unsuccessfully. It came close, but you need a lot more than just an FPGA to make a useful RC: you needs a preconfigured computing architecture to start with, otherwise the programmer needs to think in terms of gates, and that's one paradigm shift too far. The 6200 suffered from not being specific enough. That's a peculiar observation to make in the FPGA field, but it reflects reality in the computing field, and even RCs need to take that into account.

    And that's what PACT seem to have done with their XPP. Sure, its reconfigurable parts are based on FPGA technology (the only sensible way of doing it), but they've created a whole new dataflow computing engine with that RC resource, and it's the latter that's interesting for computing people, not the FPGA itself nor the internal RC mechanism.
  • why is it posts that are flamebait against MacOS are marked as "Funny"? imagine if the same thing was said against Linux?! ha
  • Another Slashdot feature was posted on the same topic within the same day, probably by mistake. Here [slashdot.org]'s a pointer to that continuation of the subject thread, for those that like to browse the archives.
  • Yeah, but everybody has to have something to do. I'm just glad that the big slobbering idiots are entertaining to watch. Nothing's funnier than watching two big stupid guys beating the hell out of eachother.

    Oh yeah, and it's not like I've got much choice. My wife watches it (for obvious reasons, I feel so inadequate), and wants me to watch it with her (I don't think it's working, I'm still fat and lazy).
  • Al Gore - Now see, you done misquoted me again. What I said was I help introduce the bill to provide funding for the development of mini-watts. G. Bush - Now I guess Gore invented the horses my daddy gave too.. (chuckle)....
  • Right now, it's not an issue for single-chip Athlon systems, but the Alpha market seems to compare performance based on the number of "D" chips in the system. The more "D" chips on a board, the better the routing and bandwidth possibilities. Athlons and single proc Alphas have 2, dual Alphas have 4 or 8.

    It does reduce the contention some, make the board easier to design, but to make best use of this on a dual processor board, you should have two independent PCI busses and two independent memory banks.
  • Maybe they are so worried about how well Linux will be ported to the IA64 they are focusing all their 64bit related resources on developing Whistler?

    Ya think? I like the idea of MS running scared ;)

    IA64 has had a large push corporation wise for Linux support, does Hammer have anyone besides AMD pushing for Linux support?

    XPU128 EXTREME PERFORMANCE

    51.2 Peak GigaOps (32 bit)
    12.8 Peak GigaMACS (32 bit)
    6.4 GigaByte/sec I/O bandwidth
    3.2 GigaByte/sec external memory bandwidth
    12.8 GigaByte/sec internal memory bandwidth
    The core of the XPU128 is an array of 128
    parallel Processing Array Elements (PAEs)
    implemented in advanced, reprogrammable technology. Each PAE performs high-speed 32-bit
    arithmetic signed and unsigned operations that execute in a single clock cycle.

    n pasted..

    It also handles clock cycles for you and handles all the syncing there, and had quite a few other things that made it seem rather impressive for running at 100 mhz and posting those kind of stats..... Imagine this thing as fast as some of todays processors..

  • Check this [chipanalyst.com] out. (Scroll down to the middle of the "PC Processors" session.)

    Pretty interesting for us PPC-heads....

  • Damn slick, although they didn't say how long the demonstration lasted, I'm dubious that it was an entire VCD but who knows. Nor did they mention how much speed the CPU lost as the voltage fell, although one could assume that it wasn't enough to hurt playback.

    Aparrently the thing can also do DSP with low power consumption.

    Maybe a super badass MP3 and video playing handheld is not that far away after all.

  • I believe a single 760MP Northbridge can only handle 2 processors, but I think AMD has hinted that you can have 2 (or more?) 760MP's on a single board, so in theory 4 or 8 way should be possible, but I expect we'll see 2-way first.
