Advantages of the Very Long Instruction Word (VLIW) over the Superscalar architecture
- The number of FUs can be increased without needing additional sophisticated hardware to detect parallelism, like in superscalars.
- VLIW is less complex than the Superscalar because VLIW. Because VLIW is implemented at the software level, all available storage space can be used. But for superscalar, its implemented in the hardware and some space will have to be allocated for the hardware so not all available storage space can be used.
Disadvantages of the Very Long Instruction Word (VLIW) over the Superscalar architecture
- Superscalar machines are able to dynamically issue multiple instructions each clock cycle from a conventional linear instruction stream while VLIW is static.
