The Visual Instruction Set (VIS), first introduced with the UltraSPARC-I microprocessor, is described from an Instruction Set Architecture (ISA) standpoint. Besides covering the functionality of each instruction individually, we look at a few widely used algorithms that can be sped up significantly (2-7X) by using VIS. The software environment surrounding VIS is also described.
