I think this model is completely wrong and should be inverted. The main CPU should be on top and run completely transparently. If you want secure coprocessors for DRM and cryptography, they should be subordinate black boxes.


Like a tpm module?


I for one would be fine with a TPM that is on its own silicon and carrier rather than on the processor die or otherwise inside the CPU package. Then I could disable it when I don't want it working, without possibly killing my processor by doing so.


Yeah, or like a HSM for example.
