Processor

Processors are devices which are used by 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.

Central/Cerebral/Core processor
It is likely that Central processor, Cerebral processor and Core processor refer to the same thing, possibly the mechanical equivalent of a biological brain. When these terms are used in figures of speech, they seem to be used in place of "mind" or "(metaphorical) heart". There are various instances where the Central-, Cerebral- or Core processor was mentioned:
 * Prowl once commented that Chip Chase was a human after his own central processor.

Logic processors
Logic processors process the information a Transformer is receiving and determine how much sense it makes. How these correlate with logic circuits is unstated.

Meta processors
Meta processors are processors which process a Transformer's conception of reality itself.

Vocal processors
Vocal processors convert electronic data intended for verbal communication into audible signals and allow Transformers to speak to their comrades.
