Jumped the SHARC

You guys have all the fun! :) I decapped a ceramic Pentium MMX, and then a coworker accidentally promptly dropped it, and it smashed into dozens of pieces before I could even look at it under the microscope. :(

The Drillenium Falcon? But its an (end?)mill bit, that would make it the Mill-endium Falcon!

I love that Master Ken, THE guy for reversing silicon dies, was thrown for a loop by the "gills" on the shark.

One intricate machine opening another intricate machine

I have a Fairlight DREAM Station that has a Fairlight QDC rack processing unit - it has a bunch of Dual core SHARCs for signal processing along with a pair of 68040 to handle I/O (U/W SCSI etc). The system is utterly wild, the QDC runs Fairlight OS, which is a custom OS/9 real time OS that's a hangover from the 6809 in the original Fairlight CMI, the console for it is a Windows XP embedded PC, more than a dozen touch sensitive linear motorised encoders, all the other controls are touch sensitive, there are three comms links between the systems; serial for command, another serial for the data to present the interface, and then Ethernet for bigger stuff - both for reduncancy and for leacy reasons dating back to the CMI. Even the power supply syncs to the word clock to avoid quantisation errors. If you can ever find an original DREAM (Digital Recording, Editing And Mixing) system - especially a DREAM Console, from before they replaced the QDC with a PC & FPGA cards, you would absolutely geek out.

This is 2007 KZread in 2023. Marvelous.

I think the gills/squares on the shark picture allude to the appearance / layout of the silicon die. There are two large rectangular regions and two smaller rectangular regions on each die. Dies visible at: t=17 Shark mascot visible at: t=32

I was quite surprised to see 4 dies instead of 1 big one! I guess that got more reliable yields though :)

In theory you get more ICs out of each wafer because they're smaller, but there's a higher risk something fails post-assembly. It's limited how much you can test each chiplet by itself, and until you integrate them all together you don't know how well they work together, so there was always some that failed testing after being fully assembled. When Intel made the Pentium Pro, which only had the core and L2 cache chip bonded together, only something like 1 in 3 passed final testing. Nowadays they've gotten better at making them so they work on first try, but ultimately the rated speed the CPU is capable of is typical a result of how well all the different chiplets play together

@@thesteelrodent1796 Not really, they just got better at testing them, there are still failures, but Intel often will cut the failed cores and bin down the silicon then sell it as a lower tier product. They are capable of testing them before they even cut the wafer.

Thank you for making a #Short #InTheRightOrientation Vertical video is a crime against humanity.

The chip company I used to work for many decades ago banned all graphic art on dies after several tape-outs were delayed due to DRC software being very confused about the "artistic" features that were sneaked in the layout.

@Mordecrox

Wonder if that's still an issue, took a primer on circuit design and learned why most circuits look the way they are, better software now finds the most optimal path being "too curvy", and now you got either options to be deliberately artistic, or maintain optimization while keeping the classic jagged edges. Yes I know those are different things (circuit boards vs die lithography) but I believe both adhered to hard physical and coding restrictions which today would be less of an issue.

I had a pentium de-capped, it has been molded in to a selastic. Unfortunately there are some bubble especially at the bound wires, but it’s pretty to look at.

Nice little easter egg!

Amazing

👍👍

For deliding, use a smaller end mill, preferably a carbide one.

I too will be very happy when shorts can be shot the right way round. Vertical just makes editing harder.

that one time you were faster on the draw than the Shirriff.

We used to manufacture ICs for Nokia, and as I was setting up an automatic visual inspection, I found a small pig !

I found the datasheet for that online. It is so epic and interesting on how that works

Just when you thought it was safe to go back in the water...

Best elevator music channel on youtube :)

Gorgeous CPU :) Interestingly, if you look at an early quad-core CPU, like a AMD Phenom, it looks very similar to this, with its four cores organized in the exact same way - only it's of course integrated on a single IC instead of multiple - simply because the early multi-core CPUs were literally "just" seperate CPUs stuck together. Modern CPUs are a lot more complicated, since they're more than just CPUs, so they look very different

Does it use FinFETs, has it got a mega bite and is it water cooled?

marc will you tell us a bit more about this nice chip ? what was it able to do and how much did it cost back then ?

Haha, fun.

So so so cool. I love silicon graffiti.

so bizarre to me that the only thing between that silicon and the top of the overall package is air. you could heat sink that package all day long, but it's just air between the silicon and the mating surface of the heat sink. I seem to recall this being a feature of early intel chips, once people got to overclocking.
