I would think that an application such as being used on the space shuttle would require an obscene amount of testing and validity checking, and that pretty much everything on a CPU needs to be tested, even features not in use, and that the code needs to be heavily tested, etc. Changing the CPUs, even to the extent of adding a few features is probably problematic, and an amazing amount of work.<br>

I would also think that the power consumption, heat output, etc are all accounted for and changing that would cause a cascade of other things needing modified or tests.<div><div></div><div class="Wj3C7c"></div></div></blockquote>
