Here we have a first idea for hardware encryption.

The black rectangle is a bidirectional circuit, where you could shift, invert or make use of logic gates.

This is absolutely nothing like BitLocker.

This is a possible protection against a direct raid on my RAM.

But it's no protection to buffer overflow, not even something like the "Meltdown" bug.

And I won't implement an "Out-of-order-execution" for my program counter and program memory logic.
