Intel has their management engine, AMD does the same and ARM architecture is shit

Too much of a hassle.

This tbh

How fast would that be compared to a standard IC?

(checked)
Just use FPGA for prototyping, then use

You design it then hand of the designs to some unknown for fab? That doesn't sound very good, especially if it's anywhere that has Chinese or communists involved, like Germany.

Who cares if they steal your design? Signals intelligence agencies won't be able to design bugs into it in the time period from you handing over your design to it being created.
And even if they had some wonder team that can do so in days (they don't), they wouldn't bother to do it for small student projects being produced on only a few wafers.
Now, if you do this over and over and they are aware you are creating non-compromised CPUs, then they might spend some time to design bugs in future versions and approach the fab, but more likely they would approach you first, so you would know they know about your operation.
Easy way to avoid this is just make all you need in a couple of years and then sell them AFTER they've been fabbed.
Also, since you're putting them together, you could image them under a microscope and see if the layout matches your design.

Do you have any proof about what you are saying, because otherwise doubt is not a reason for trust.

Also, the
is dismissing the fact that all large FPGAs are botnetted!
It's like saying you're buying an intel cpu for a 'secure desktop' you're building and then saying

Learn how much time it takes to design a complex integrated circuit, and then determine the time required to modify the design in a way that compromises its security and is difficult to detect.
You are implying they can do so in a short period of time, which is a much bigger assumption IMO.
Also, since you can view the final product under a microscope and match it to your own design, the point is moot.

I am less worried about them introducing new designs and more worried about them finding flaws in the design and exploiting it that way.

That's a good point. Only a verifiably correct and bug free design (not sure if possible for hardware and would probably make design take 10x longer) could alleviate that risk.
And even if one were able to produce verifiably correct hardware on a design level, I just discovered this
sharps.org/wp-content/uploads/BECKER-CHES.pdf
which would make microscope analysis of the finished product useless for detecting introduced bugs.

Still though, I think FPGAs with coprocessors on them are a bigger risk.

The ice40 FPGA series are the only FPGAs (there are no CPLDs or ASICs ones) who can be programmed with an entirely free toolchain (from a HDL to the bitstream you send the FPGA) meaning you don't need to use any huge, bloated, and proprietary IDEs by the manufacturer.

The microprocessor I'm currently designing is targeting one of the higher end ice40s. It's kind of a fun project and am planning to at least support VGA and PS/2 connectors so I can use it as a simple computer.

Thanks for the list. Raspberry Pi isn't listed, and I also remember reading somewhere that it has something like Intel's management engine in it. Do you have any information about it?

For that one, it needs a binary blob to even boot properly, afaik

Is there somewhere I can read about this?

Probably about 100-400 MHz.

There are several threads in the catalog on this exact subject

Ehh. I wonder how bad they are after coupling that with their IPC.

Librebooted ThinkPads are unstable in terms of performance (probably the lack of microcode). That's why I'd recommend a POWER9 workstation over everything.

Basically this and only this from a practical perspective, everything else is RPi-tier in terms of performance.

Power8 and newer supports both BE and LE you mongoloid, the CPU firmware selects which mode at boot and by default selects LE. Thats why Canonical and such list PPC64LE

Even using MPW you are still looking at thousands of dollars per 1MM^2 for old processes like 40nm and tens of thousands for newer processes like 14nm.

TSMC and other large fabs deal with thousands of customers a year for their shuttle service, do you really think they are going to destroy their reputation by going out of their way to reverse engineer a CPU designed by some nobody just so they can insert hardware backdoors into a CPU which is going to be used by a grand total of one person? You are delusional as all hell. Reverse engineering even a small CPU from the masks is like reverse engineering a compiled binary by hand without knowing what each instruction actually is.

Slow, I remember seeing something about Nvidias massive clusters of FPGAs they use to prototype GPUs and they run at a fraction of the speed that the final product does.

Probably on the lower end of that for anything larger than a Microblaze or generic MIPS processor.

Industrial espionage is a real thing.

I know, but last time I checked the guy I was responding to probably isn't Jensen Huang or Lisa Su and it was TSMC being mentioned and not some no name fab in China. TSMC and Global Foundries aren't stupid enough to physically alter designs because their business depends on large companies trusting them with their IP.

Also a reminder TSMC (Taiwan Semiconductor Manufacturing Company) is NOT Chinese no matter how much the putrid soulless Chink drones try to take over Taiwan's national identity and turn it into a puppet state

Allegedly, even the RPI boards can use open firmware nowadays. The FSF has a page about this, but it appears to be outdated:
fsf.org/resources/hw/single-board-computers
Anyway there's so many ARM boards to choose from, you don't have to buy RPI. Pick whichever one fits your needs.
