Which of the following describes a computer processing architecture in which a language compiler or pre-processor breaks program instructions down into basic operations that can be performed by the…
The correct answer is A. Very-Long Instruction-Word Processor (VLIW). VLIW (Very Long Instruction Word) architecture relies on the compiler (not the hardware) to identify and bundle multiple independent operations into a single long instruction word that the processor executes in parallel. This shifts the complexity of finding parallelism from…
Question
Which of the following describes a computer processing architecture in which a language compiler or pre-processor breaks program instructions down into basic operations that can be performed by the processor at the same time?

- AVery-Long Instruction-Word Processor (VLIW)
- BComplex-Instruction-Set-Computer (CISC)
- CReduced-Instruction-Set-Computer (RISC)
- DSuper Scalar Processor Architecture (SCPA)

Explanation
VLIW (Very Long Instruction Word) architecture relies on the compiler (not the hardware) to identify and bundle multiple independent operations into a single long instruction word that the processor executes in parallel. This shifts the complexity of finding parallelism from runtime hardware to compile time. CISC (B) uses complex hardware-executed instructions, RISC (C) uses simplified instructions, and Super Scalar (D) uses hardware logic to dispatch multiple instructions in parallel - not the compiler.
