    It owes its simplicity to the predecoding of the I/O (input/output) slot address already provided on the Apple's main circuit board.

    1985, Steve Ciarcia, Ciarcia's Circuit Cellar, revised edition, volume 5, Circuit Cellar, page 32

    Predecoding shifts a part of the decoding task up into the loading phase of the on-chip instruction cache (I-cache)... A dedicated unit called the predecoded unit executes partial decoding and joins several decode bits to each instruction.
