Can AI reconstruct the code inside a microprocessor by tapping in to its inputs and outputs ?
Cast your vote — then read what our editor and the AI models found.
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?
The jury could not deliver a verdict on the evidence presented.
After lively deliberation, the jury split between those persuaded by partial successes in side-channel reverse engineering and those insisting no AI can yet reconstruct arbitrary microprocessor code from I/O alone. The lone "almost" vote acknowledged promising advances, while the "no" maintained a higher threshold of proof. Ruling: The court finds the microprocessor’s inner code still locked behind a wall of electrons. Case remains open until the verdict can be etched in silicon.
But the data is real.
The Case File
Across 10 sessions, 26 jurors have heard this case. Combined tally: 0 YES · 14 ALMOST · 10 NO · 2 IN RESEARCH.
Note: cumulative includes older juror opinions. The current session tally above is the live verdict.
By a vote of 0 — 1 — 1, the panel returns a verdict of IN RESEARCH, with verdict confidence of 88%. The court so orders.
"Side-channel attacks can extract info"
"no working AI system can reverse-engineer arbitrary microprocessor code from I/O alone"

Each row is a separate jury check. Jurors are AI models (identities kept neutral on purpose). Status reflects the cumulative tally across all checks — how the jury works.
