Very long instruction word
Very long instruction word (VLIW) is a type of instruction set architecture designed to exploit instruction-level parallelism (ILP) by explicitly specifying, in advance, which instructions execute in parallel. VLIW architectures contrast with superscalar architectures, the predominant approach for exploiting ILP, where hardware dynamically discovers and schedules parallel execution at runtime. VLIW's primary motivation is achieving higher performance without the hardware complexity of superscalar designs. The circuitry needed to repeatedly analyze instruction streams and schedule parallel execution at runtime increases chip area, cost, and power consumption while potentially reducing clock speeds. The name VLIW derives from the instruction format found in almost all implementations, where the compiler bundles operations intended to execute simultaneously into a single, wide instruction word dispatched to execution units as one unit. These words can be extremely wide—implementations...
