predecoding
/ˌpriː.dɪˈkoʊ.dɪŋ/
Meaning
The process of partially decoding machine instructions prior to their storage in the instruction cache, typically to identify instruction boundaries, classify instruction types, and facilitate faster
present participle and gerund of predecode
The process of partially decoding machine instructions prior to their storage in the instruction cache, typically to identify instruction boundaries, classify instruction types, and facilitate faster or parallel decoding during execution.
The process of partially decoding machine instructions prior to their storage in the instruction cache, typically to identify instruction boundaries, classify instruction types, and facilitate faster or parallel decoding during execution.
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.
Etymology
From pre- + decoding.
