Introduction
Intel has a long history of innovation in adding new capabilities to computer architecture and enabling
the industry to deliver advanced applications with greater performance and capability. From the original
Intel?8086 to the recent addition of Supplemental Streaming SIMD Extensions 3 (Supplemental SSE3)
found in Intel?Core.2 Duo processors, Intel has led the charge in expanding the capabilities of the world’s
most popular and broadly used computer architecture-Intel?architecture. Continuing the history of
innovation, this latest expansion of Intel architecture constitutes the most impactful instructions
since SSE2 and represents the next major leap in Intel’s fast-paced trajectory to deliver products
with superior performance, capability, and energy-efficiency for years to come.
Building on the already rich Intel?64 instruction set
architecture (ISA), these new instructions will enable our
microprocessors across all volume market segments to deliver
superior performance and energy efficiency to a broad range
of 32-bit and 64-bit applications. These new instructions include:
?Streaming SIMD Extensions 4 (SSE4)
that will provide building blocks for delivering expanded
capabilities, enhanced performance, and greater energyefficiency
for most…
