The Intel Itanium architecture (formerly known as IA-64) is a 64-bit platform used in high-end computing (eg: scientific research) and high-end, enterprise servers. The architecture is based around the idea of instruction-level parallelism. More specifically, it utilizes E.P.I.C. (Explicitly Parallel Instruction Computing).
Instructions are sent to the processor in "bundles", with 3 instructions per bundle. Each bundle is 128 bits in width with a 5-bit template field specifying the encapsulated instructions. Each instruction is an awkward 41 bits in size and certain bundles contain "paired" instructions known as LX Units (allowing for a 64-bit immediate).
