Processors are devices which are used by the Transformers which process information and relate it to the individual mechanoid. Their increasing use in describing mechanoid anatomy (as opposed to attributing everything to circuits) can in some ways be attributed to the fact that writers within the Transformers franchise actually know how computers work now.
- Cerebral processors
Cerebral processors (or brains) are devices which process the internal information that is going through a Transformer's mind. When Ratchet said that the Autobots will not leave without Optimus Prime and Bumblebee, the Autobot leader told Ratchet that such a thought would never have entered his cerebral processor.
- Core processors
Core processors are devices which process information and reality. Megatron noticed that the Key had altered Soundwave's core processor beyond what he had originally intended. Additionally, Bumblebee thought that Bulkhead may have taken a few too many hits to his core processor.
Logic processors process the information a Transformer is receiving and determine how much sense it makes. How these correlate with logic circuits is unstated. When Shockwave was attacked by the Dynobots, he shut down his logic processor and allowed a "rage" program to take control, letting him win the battle.
Meta processors are processors which process a Transformer's conception of reality itself. After his stint on the plasma baths of Thrull , Galvatron's meta processor was seriously embrittled due to the amount of time he spent on Thrull. It also drove him completely psychotic, to the point where he alternated his time between violently attacking the Autobots and violently attacking his own Decepticons. The psychiatrists of Torkulon attempted to repair his damaged psyche through every available means (except actually replacing the damaged parts of the meta processor) and eventually decided to let Torkulon itself consume Galvatron's meta processor and madness. This actually turned out very badly for the Torkulons.
Vocal processors (literal voice boxes) convert electronic data intended for verbal communication into audible signals and allow Transformers to speak to their comrades. Bumblebee's vocal processors were damaged in battle with Megatron. Although he was still able to communicate through a number of internal frequencies, his lack of a voice made the Autobot feel as though he was failing his comrades. How these correlate with oral circuits is unknown. In close-ups of the Transformers with mouth open (no, not the dull surprise), a spinning metallic flat cylinder-kind of device is seen, which appears to be at least related to the vocal processor.
These were computers that held the consciousness of a Transformer. Prowl entered Omega Supreme and accesed his internal processor in order to free the giant Autobot from Megatron's control. However, Megatron was also present within the processor and attempted to stop Prowl before Omega Supreme took command once more and ejected Megatron from his controls.
