Examples

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

“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.”

“Predecoding enables reduction of decoding latency and an area-efficient layout.”
