439 being a prime would be an issue if you were up multiplying a lower frequency to generate it, for example using a PLL. However it is such a slow signal that it would be generated by dividing down a higher frequency. For example you can d

For the same reason Hollywood promotes "Glamour", "Celebrities" and fawns over them on the red carpet. Gotta feed the machine with the bright-eyed and the impressionable.

Very good read! But, in fairness this isn't a failure of the S905 SOC. It is a bug in the second stage bootloader that fails to authenticate the next image. The SoC BootROM validates the RSA signature of the second stage bootloader.

The media block has a small micro inside the controls the HSM. It runs on an internal back-up battery. If the unit is opened, or tampered with then it wipes all the keys. That module is FIPS certified against intrusion.

They wouldn't send a DCP stream for transcoding. DCP stream can only be decoded by the media block inside the projector and the output physically goes to the projector chip. The system has safe guards against physical intrusion. If y

Time will tell. DCP has a lot of security built-in. Both in hardware (FIPS certified, anti-intrusion, etc.) and in Software -- encryption up the wazoo. Studios rely on a lot of insecure distribution and storage mechanisms for the big DCP fi

It is mostly based on my experience working as an ASIC designer and having taped out several chips. However, you can consider it logically -- the engineering effort to design the logic, and perform place and route doesn't change much f

I've been involved in design of an ASIC that used a customized Tensilica DSP, circa 2009. The custom instructions were the main reason we opted for that core. There are a ton of other customizations that you can make with Tensilica s

That's the recurring cost of the mask set, because they don't last forever. The setup cost of the mask however is very high. As for logic design effort, verilog is verilog. Floor-planning and P&R is a bit more complex at lower

by bravo22 10y ago
The "design" cost quoted mostly means mask cost. It gets very expensive to produce for smaller nodes.

1) Indeed. 2) You can debounce reliably in hardware.

Yes. That's exactly what it means. You can have priorities for different interrupt sources. It has utility in many critical RTOS situations. Imagine you have a factory machine. The micro has an IRQ for your communication interface. Thi

Any company IP would be cheaper to pick-up in a post shutdown sale. It isn't the VCs personal money they invested, but they do have a lot of personal relationships which could pay off in the future for strategic reasons. You don't

I think the article meant the overall numbers are insignificant, as opposed to it being insignificant as a percentage of the actual funds.

I imagine they would log all the inputs, as well as branches taken so they can later replay everything in a debugger. That would make the process much simpler.

I found that to be a bad argument as well. The author is conveniently ignoring the fact that those options vested in the first place. By that logic, why should investors get a lot of the windfall when they didn't "work hard"

This is not uncommon. Usually a product "family" is all from the same wafer. During packaging and testing either certain pads are not bonded out or certain fuses are blown out (via laser cutting, or as an efuse) to disable certain

My post was in response to: "I think the biggest problem here is that we have too much media coverage and scrutiny on stuff like this today". The coverage happens because Google talks about it; irrespective of merits of taking ris

True. However Google PR tells the media about these bets in the first place. It used to be the case that R&D was kept under wraps. I'm sure a number of projects fail at Apple too but we never hear about them because Apple doesn&#x2

Yes. It is very popular for high-end FPGA use cases. Essentially instead of relying on the built-in routing matrix which makes FPGAs what they are, they modify the metal layer and connect the chip per your design as an ASIC. You get much lo

by bravo22 10y ago
True. That's another possibility. I'd imagine since they'd want to squeeze every performance per want out of the chip they'd want to go for smallest node possible. Virtex7 EasyPath is 16nm! It is pin to pin compatible wi

by bravo22 10y ago
Unless they're doing 100K plus for 2-3 year life of a chip, it makes sense to stay w/ EasyPath or the Altera Hardcopy. It is much easier and more flexible for making revisions. Consider that they will most likely make another vers

Given the insane mask costs for lower geometries, the ASIC is most likely an Xilinx EasyPath or Altera Hardcopy. Otherwise the amortization of the mask and dev costs -- even for a structured cell ASIC -- over 1K unit wouldn't make much
