sse3-support - 15.1 main

The packages in the isa-support family probe for microprocessor Instruction
Set Architecture features such as SSE3. By refusing to install on machines
lacking a required feature, they allow ISA requirements to be handled in
terms of package dependencies.
.
This is a mostly dummy package which checks for SSE3 and refuses to install
on unsupported hardware.
.
Streaming SIMD Extensions (SSE) is a single instruction, multiple data
(SIMD) instruction set extension.
.
SSE3, also called PNI (Prescott New Instructions), is an incremental upgrade
to SSE2, adding a handful of new operations useful for processing media. It
is available on almost any 64-bit-capable processor except for some early
AMD models (Sledgehammer and Clawhammer), but is not available on most
32-bit-only hardware.
