According to the demand on enor- mous multimedia data processing, we have designed a VLI W(Very Long Instruction Word) processor called DIVA(Dua1-Issue VLIW Architecture) ex- ploiting the ILP(instruction-level parallelism) in multimedia programs. DIVA processor which can execute two instructions in one cycle supports 86 instructions including 30 media instructions, and has a sub-word execution structure that supports the satu- ration mode arithmetic for image processing. Com- pared to scalar architectures without media instruc- tions, the performance of the DIVA processor is im- proved by 2.2 to 5 times due to the combination of VLI W architecture and media instructions.
