VOLK is the Vector-Optimized Library of Kernels. It is a free library,
|
||||
currently offered under the GPLv3, that contains kernels of hand-written SIMD
|
||||
code for different mathematical operations. Since each SIMD architecture can
|
||||
be very different and no compiler has yet come along to handle vectorization
|
||||
properly or highly efficiently, VOLK approaches the problem differently.
|
||||
|
||||
For each architecture or platform that a developer wishes to vectorize for,
|
||||
a new proto-kernel is added to VOLK. At runtime, VOLK will select the correct
|
||||
proto-kernel. In this way, the users of VOLK call a kernel for performing
|
||||
the operation that is platform/architecture agnostic. This allows us to
|
||||
write portable SIMD code that is optimized for a variety of platforms.
|
||||
|
||||
VOLK was introduced as a part of GNU Radio in late 2010 based on code released
|
||||
in the public domain. In 2015 it was released as an independent library for
|
||||
use by a wider audience.

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
