Is it possible to work out exactly what code or logic is running inside a microprocessor just by watching its input and output signals? Current technology falls short of recovering the full internal instruction set or circuitry, but researchers can still extract glimpses of behavior through subtle side effects such as power use, timing, or electromagnetic leakage.
Background
Reconstructing the internal code or logic of a microprocessor solely by monitoring its inputs and outputs is currently beyond the capabilities of existing technology due to the complexity and scale of modern processors. Side-channel analysis and reverse engineering techniques can infer some internal behavior through power consumption, timing, or electromagnetic emissions, but these methods cannot fully reconstruct the processor's microcode or circuit design. The sheer number of transistors, layered abstractions, and obfuscation from encryption and proprietary architectures make complete reconstruction infeasible with non-invasive methods. Advanced techniques such as decapping and electron microscopy are required for detailed internal analysis, which go far beyond simple I/O monitoring.

Can AI reconstruct the code inside a microprocessor by tapping in to its inputs and outputs?
Juryen kunne ikke afsige en dom på det fremlagte bevis.
Juryen kunne ikke blive enige om, hvorvidt sidekanal-chatter udgør en fuld rekonstruktion, så den uafgjorte jurymedlem splittede vægtskålen ved at afgive en "i forskning"-stemme – hvilket efterlod resten af panelet ligeledes ude af stand til at nå til enighed. Dommen afhænger ikke af umulighed, men af dagens usikkerhed: vi kan høre koden hviske, men endnu ikke læse den højt. Domsafgørelse: Mikroprocessorens indre liv forbliver en lukket bog med sider, der blafrer lige uden for rækkevidde.
The jury could not agree whether side-channel chatter amounts to full reconstruction, so the undecided juror split the scales by casting an “in research” vote—leaving the rest of the panel likewise unable to reach consensus. The verdict hinges not on impossibility but on today’s uncertainty: we can hear the whispers of the code, yet not yet read it aloud. Ruling: The microprocessor’s inner life remains a closed book with pages fluttering just out of reach.
But the data is real.
The Case File
By a vote of 0 — 1 — 0, the panel returns a verdict of UNDER UNDERSøGELSE, with verdict confidence of 65%. The court so orders.
"No demonstrated capability to reconstruct proprietary microprocessor code from I/O alone."
"side-channel attacks can extract some information"
