Instruction set: The architecture gives instructions for multimedia operations and floating point operations.
The Itanium supports various bundle mappings to allow for more instruction mixing possibilities, which contains a balance among serial and parallel implementation modes. There was room left in the initial bundle encodings to add more mappings in future versions of IA-64. In addition, the Itanium has individually settable predicate registers to issue a type of runtime-determined "cancel this command" directive to the respective instruction. This is sometimes more efficient than branching.
