34 Design Flaws in 20 Days of Intel Core Duo 356

Pray_4_Mojo writes "Geek.com is reporting that Intel's errata (bug) documentation shows that the Intel Core Duo chip has 34 known issues found in the 20 days since the launch of the iMac Core Duo. (you can read the list) with only plans to fix one of them. While bugs in hardware is nothing new (the P4 has 64 known issues, at this time Intel does not plan to fix a single one) this marks one of the first times that Intel released a processor with known bugs, and some of the bugs are of higher severity than in the past. Also alarming is the rate the flaws have been found, at one and half per day since the launch of the iMac Core Duo."

        Indeed! It's like you would say that it's much easier to find bugs just after the first release of the CPU and even easier when it's the debut of a completely new architecture like the Core Duo is!. It'd be like posting links to the AMD errata docs!

        like bugs in CPUs are something new....I want to know how many bugs where found in the first 20 days of the release of other intel architectures and the opteron, otherwhise I can't know if the core duo is a bad CPU compared with others or not. This article just looks like anti-intel FUD from AMD fanboys (Intel made a good CPU even with the bugs, deal with it, AMD is not going to give away free CPUs to you for being a fanboy).

        And let me doubt that there's any CPU manufacturer at all that releases CPUs without any "know bug", many CPU bugs are fixed with microcode updates via new bios versions. There's a reason why both amd and Intel CPUs allow to update the microcode, they don't include features for fun.

        Given the fact that a very substantial part of the extra chip estate is being used as L1 and L2 chache, the error rate should increase less than proportionally. If you upgrade cache size from say 8 kB to 1 MB, then there is only a relative small increase in complexity of the cache controler, not of the cache itself.
        Add the new chip design software and the use of hardware libraries for standard chip functionality, then the error rate should increase even slower.

        I'd expect very close to no bugs in either. The costs involved in carrying out comprehensive design analysis, specification verification and implementation verification are virtually zero compared to the cost of producing the initial run of actual silicon.


        You also have to bear in mind that designs are modular and have limited connections, so N transistors is not a meaningful number - you should only be concerned with the number of modules and the number of interconnects. (eg: a 32-bit register will obviously take more transistors than an 8-bit register, but both are simply cut-and-paste copies of a 1-bit register. So long as you have the 1-bit form correct, there is no increase in complexity no matter how wide the register becomes.)


        As for the interconnects - if you have N modules, you have an upper limit of !N possible interactions, if you can string any possible combination together. That's a big number, even for small values of N. But most of those don't exist. You cannot feed the output of one operation directly into the input of another. There are some special cases where there is a chain of events, but it is not something you can program with total freedom. Many operations just produce a result which is pushed back into the registers. Thus, N modules will produce only a little more than N interactions of interest. That is a much more managable number.


        Then you need to consider that processors aren't "open floor plan". They are highly segmented. The term "floating point unit" literally does refer to a definable segment of the chip that is designed for floating point work. Again, from the standpoint of reliability, you can test each unit independently before doing an integrated test, so unit tests don't need to concern themselves with overall complexity or the number of other units out there.


        Next up is the cost of a recall. Recalls are expensive. From a pure profit standpoint, you want to spend less on QA than you'd spend on a recall, but the less you spend on QA, the more you are likely to end up spending on that recall. The ideal is to reduce the number of potentially serious bugs to the point where any further initial clean-up will cost more than the money lost in cleaning up afterwards. Less QA than that will cost more than it saves. More QA than that will also cost more than it saves unless it expands the market (ie: the chip becomes good enough to be used in mission-critical systems such as life-support or fly-by-wire systems), but is sometimes good to do anyway for PR reasons.


        Finally, not all transistors are "important". Once you know the cache algorithm works, the actual cache memory is irrelevent - memory is rarely implemented "incorrectly", it doesn't "do" anything (the active part is the algorithm), it's just heap.


        With modern software verification tools, chip validation suites and the high level of understanding of microelectronics, an average of one bug for every four or five instructions is high. I would consider a chip with a third as many bugs to be only just acceptable for home use, and a thirtieth as many for operations in which any significant number of people would be put at risk. The extra cost would be minimal (compared to all the other costs) and would still be much less than the cost to Intel of the Pentium divide bug or to Transmeta of the flaws in their initial Crusoe chips.

          I think your estimates are *way* off.

          Silicon fab facilities are extremely expensive and capital intensive, but they produce shitloads of chips. The process scales; making 1000 wafers in these fabs is as easy as making one.

          Engineering analysis of complex IC designs is a perfect example of combinatorial explosion. Each bit of state in the chip doubles the state space in which bugs can exist. Yes, *most* of that state is in the cache which has regularity in its structure, but that regularity didn't happen by accident: it was *designed* that way.

          You can only test to a spec, and if the spec is imperfect and has gaps, you will leave space for bugs. Given that specs are written by engineers, they cannot be nearly complete for anything other than the most trivial circuits; the infrastructure used to suppor engineering of non-trivial circuits could itself have bugs.

          The part of the spec that covers the cache is simple, and can conceivably be error-free and well-tested, and perhaps with methods that are amenable to mathematical proof. But that's not where the errors crop up. The errors crop up in the hugely complex mechanisms that handle all the pipelining, branch prediction, translation to microinstructions, handling of interrupts, etc., etc., that are not highly regular and modular and are not easy to spec, and are not easy to approach with formal methods.

      ... for the first time, they're releasing the chip for a stable OS first.

      It used to be that testers only had an unstable testbed OS (designed primarily to run the same company's office suite) to use for validatation. Testers were never quite sure before where the blue screens, lockups, funny noises, and billowing smoke actually originated.

    It's a little disohnest to use the phrasing "Core Duo chip has 34 known issues found in the 20 days since the launch of the iMac Core Duo."

    Most of these bugs were found well before the release of Core Duo. Many of the bugs are listed as having been observed by Intel only. That means the verficiation teams did hit these issues, either with very bizarre code setup, or doing something that's probably not technically legal anyway. Odds of seeing most of it in an end-user platform are very unlikely.

        http://www.amd.com/us-en/assets/content_type/white _papers_and_tech_docs/25759.pdf [amd.com]

        There's a lot more listed there than for the Core Duo so far, and quite a few marked as "Won't be Fixed" and are scary sounding. Here's an example of a rather nasty looking ordering bug that results in system hang:

        Downstream non-posted requests to devices that are dependent on the completion of an upstream
        non-posted request can cause a deadlock in the presence of transactions resulting in bus locks, as shown in the following two scenarios:

        1. A downstream non-posted read to the LPC bus occurs while an LPC bus DMA is in progress. The legacy LPC DMA blocks downstream traffic until it completes its upstream reads.

        2. A downstream non-posted read is sent to a device that must first send an upstream non-posted read before it can complete the downstream read.

        In both cases, a locked transaction causes the upstream channel to be blocked, causing the deadlock condition.

        Potential Effect on System
        The system fails due to a bus deadlock.

When Intel had its famous FDIV bug, they shipped it knowing that the problem was there (the chips were already manufactured before they noticed it in their internal design validation.) In fact I would highly doubt that any Intel chip (or AMD chip) has shipped without some known bugs in them.

    It's called "errata", and it's common for most processors to be released with pages and pages and pages of errata.

    Of course, what happens is that the alpha/beta silicon ships to select customers without many errata (though internal testing often finds them too, and they ship with those). Then the manufacturer goes back, resolves a few, then the cycle repeats until everyone is happy with the bugs and it's released with a book of errata on them, and workarounds for the severe ones.

    "No fix" errata are common. The most serious of those have workarounds. Fixed errata are for things where there can be no possible software workaround. But there's a large number of varying severity - from cache incoherences, lock failures (you try to lock something, and it either can't be unlocked the usual way, or it doesn't reliably indicate lock), to bus and spec violations.

    Nothing new here...
    • My favorite processor errata was for the engineering sample release of the Motorola PowerPC PPC5554 "Copperhead" embedded processor.

      The clock multiplier was software-settable as a 5 bit value. I.E. you could have a multiplier from your crystal of 1x, 2x, 3x, ...., 30x, 31x, 32x.

      Bits 1, 2, and 3 could be set normally. Bits 0 and 4, however, could not be changed.

      At all.

      How they managed to make only the middle 3 bits of a 5 bit register accessible, I have no idea.

    As an ASIC designer, I have produced my fair share of silicon bugs. Chips are expensive to produce, making bugs expensive to fix. As a result, chip designers (even ones with deep pockets like Intel) do not look at bugs as something to FIX, but rather as something to MASK. I don't mean to hide it from people (although that does happen), but to make it not a bug by working around it.

    Unless the bug is so fatal that you can't work around it, or the bug could potentially cost lives, the primary solution is to work around it. Either you write driver code to avoid the bug, or you find some other cheap solution. Sometimes, it's a simple matter of removing a feature from your marketing literature.

    Intel's typical means to mask processor bugs is microcode. This hurts performance, but they can typically create a workaround that routes everything around the bug. I can't read the article (it's slashdotted), but I'm sure that by saying they won't fix some bugs, they're saying that they won't respin the silicon but rather mask the bug in some other way.

    Listing the bugs (and not fixing them in this version) is an appropriate thing for Intel to do.

      "Intel's typical means to mask processor bugs is microcode."

      That's true. Every Intel CPU since the Pentium Pro can update its microcode. Many times, BIOS will contain microcode updates from Intel. Linux also has a microcode update driver [urbanmyth.org].

      "I'm sure that by saying they won't fix some bugs, they're saying that they won't respin the silicon but rather mask the bug in some other way."

      I'm not sure about that. "Will fix" seems to imply the errata could be fixed in silicon or microcode, while "Will not fix" means it won't get fixed at all.

      • I'm not sure about that. "Will fix" seems to imply the errata could be fixed in silicon or microcode, while "Will not fix" means it won't get fixed at all.

        A workaround isn't considered as a FIX, WONTFIX is wontfix even with published workarounds (including microcode). WONTFIX means that the error won't be fixed at the silicon level, which is the subject of errata papers.

  • Being in the Aerospace/Defense industry, this is disconcerning, especially for those of us that deal with the FAA and the imfamous DO-178B. Higher demanding systems are forcing us to use more powerful processors and if they are plagued with "known issues" it may be a problem with getting through a certification by some governing agency. Especially now that DO-254 has reared its ugly head... Has Intel gone the way of Microsoft? Delivering early to gain market even though the product has sever quality iss

    Coral Cache of the image [nyud.net]

    Quoth the image: Show stopper, but only observed by Intel so far. Also, any OS developer who codes like this deserves this one.
  • Next week they'll take on the difficult subject of "changelogs" and the mysterious "READMEs" you see everywhere.

  • "with only plans to fix one of them. While bugs in hardware is nothing new (the P4 has 64 known issues, at this time Intel does not plan to fix a single one) "

    Is it just me, or do the statements "with only plans to fix one of them" and "does not plan to fix a single one" conflict with one another?

    Let's not just moderate comments.

    I want to be able to moderate articles for depth, due diligence, and bias.

    This one's going to sit at top level for quite some time, trolling in everyone until they read the comments and discover they shouldn't have bothered.
  • Description of AE4 and AE11 are the same except that AE11 doesn't have the parenthetical explaination of the REP MOVS instruction. AE4 is called a show stopper, AE11 characterizes it as a mere performance issue.

    I've heard rumors that some small PC manufacturers, such as Dell and Gateway are selling computers using this cpu.
  • Just leave it in "BETA" google does a good job at that.
  • One notable bug turned into a features was the A20 Address Line [firingsquad.com] thing.
  • This is coming from the company that gave IDE a fighting chance against SCSI when it introduced IDE busmastering on it's 430 series chipset. This is the same company that made the 440BX chipset which was possibly one of the most popular chipsets for it's time. It featured new advanced core logic. Most boards with that chipset would let you use Celerons, Pentium II's and Pentium III's. Of course BIOS updates allowed more multiplexors in many cases. Intel was good about putting out driver updates on alot of i
