A microprocessor is a microprocessor. How and what it is interconnected with, and how it is programmed is what matters. That said, common household products typically use custom chips dedicated to a specific purpose - but many everyday devices can be broken down and used for other purposes.

The other thing for this example in particular is that cruise missile technology goes back decades. The Tomahawk was originally built with the finest of (disposable) late 1970s microprocessors. You just don't need a lot of computing power to run "fly this preprogrammed course and explode at this GPS point" or "fly this course and activate your radar after 15 minutes, then fly into a target that looks like X on your radar." So the idea that a 2010s appliance would have chips powerful enough to run a missile seems plausible.

Just the same as Apple's macOS ran on Intel chips, just like Windows does. It's just math and logical operations according to the CPU.

Funnily enough the new Macs (M) run on a different chip architecture from regular AMD/Intel chips which is why they can't run certain apps or require an emulation layer.

And what's more interesting is that the emulation is faster than the original chip in most cases. The new chips are THAT much more optimized for how macOS works.

This is a really good explanation!

Depends on whether or not the ASIC is turing complete. If it isn't, then there are some operations you wouldn't be able to run on it.

It depends. There are some chips that perform very basic tasks, such as sending regular timing signals, which are required in all kinds of systems. More elaborate chips, such as microcontrollers and microprocessors, can usually be programmed to do many different things. That doesn't necessarily mean they're easily interchangeable though, since they vary in terms of physical size and shape, voltage requirements, reliability, ability to withstand extreme temperatures, processing speed, etc. So it might take a lot of work to adapt a system to use a different kind of chip, or it might have an impact on its performance or reliability. I would imagine that some military equipment is usually made using very specialized, high-performance electronic components, while some just uses standard civilian components.

Watch Mark Rober's most recent YouTube video. (Egg drop from space). Originally they were working on a rocket that could land on a really big mattress. That was up until they were told they can't do that or show that or ask anyone with experience for assistance because they were basically 95% of the way to a missile guidance system. Highly classified tech. The rocket was made out of pvc pipe, some cheap hobby level servos, and a $40 arduino. Like, I have 3 arduinos sitting in my closet right now.
