Q. Registers used in IA-64 architecture ?

Registers: The IA-64 architecture comprises a very generous set of registers. It has an 82-bit floating point as well as 64-bit integer registers. Additionally to these registers, IA-64 adds in a register rotation method which is controlled by Register Stack Engine. Rather than typical fill/spill or window mechanisms used in another processors, Itanium can rotate in a group of new registers to accommodate new function parameters or else temporaries. Register rotation mechanism united with predication is too very effective in executing automatically unrolled loops.
