The disclosures show a thoroughly modern instruction set with a range of multimedia instructions and prefetch capabilities. Although IA-64 includes many RISC concepts, the architects added some rather complicated and special-ized instructions. Concerns remain, however, about code density and just how much of an advantage these new fea-tures will provide over a standard lApplication Instruction Set Architecture Guide – Complete disclosure of IA-64 application architecture lResult of the successful collaboration between Intel and HP Internet, Enterprise, and Workstation IA-64 Solutions Enterprise Technology Centers Application Solution Centers Operating Systems Tools

Three 41-bit instructions are packed into a 128-bit word; the remaining 5 bits used to guide the hardware on available parallelism. IA-64 also introduced speculative loads [21]. Chapter 10, “IA-64 Operating System Interaction Model with IA-32 Applications” defines the operation of IA-32 instructions within the IA-64 System Environment from the perspective of an IA-64 operating system.

Notice:The Intel®64 and IA-32 architectures may contain design defects or errors known as errata that may cause the product to deviate from published specifications. Current characterized errata are documented in the specification updates.

How to Use the System V ABI for Intel® ItaniumTM Processors The Itanium architecture supports a 64 bit instruction set and also provides compatibility with the IA-32 instruction set. Binaries using the Itanium architecture instruction set may program to either a 32-bit model, in which the C data types int and long and all pointer types are 32-bit objects (ILP32); or to a 64-bit model, in Technically-oriented PDF Collection (Papers, Specs, Decks, Manuals, etc) – pdfs1/AMD64 Architecture Programmer’s Manual – Volume 1 – Application Programming (24592, r3.21, Oct-2013).pdf at master · cryopie/pdfs1 Volume 2A: Instruction Set Reference, A-M NOTE: The Intel 64 and IA-32 Architectures Software Developer’s Manual consists of five volumes: Basic Architecture, Order Number 253665; Instruction Set Reference A-M, Order Number 253666; Instruction Set Reference N-Z, Order Number 253667; System Programming Guide, Part 1, Order Number 253668; System

Introducing the IA-64 architecture

Starting in 1994, the joint HP-Intel IA-64 architecture team leveraged this prior work and incorporated feedback from compiler and processor design teams to engineer a powerful initial set of features. They also carefully designed the instruction set to be expandable to address new technologies and future workloads. Information in this document is provided in connection with Intel products.

The first document describing the new instruction set was published by Intel in May 1999. The name IA-64 was published beforehand, and some of the features were known beforehand (predication and wide-issue were discussed in December 1997 on comp.arch).
