// adv-simd.h - written and placed in the public domain by Jeffrey Walton
|
|
//
|
|
// The SIMD based implementations for ciphers that use SSE, NEON and Power7
|
|
// have a commom pattern. Namely, they have a specialized implementation of
|
|
// AdvancedProcessBlocks which processes multiple block using hardware
|
|
// acceleration. After several implementations we noticed a lot of copy and
|
|
// paste occuring. adv-simd.h provides a template to avoid the copy and paste.
|
|
//
|
|
// There are 8 templates provided in this file. The number following the
|
|
// function name is the block size of the cipher. The name following that
|
|
// is the acceleration and arrangement. For example 4x1_SSE means Intel SSE
|
|
// using two encrypt (or decrypt) functions: one that operates on 4 blocks,
|
|
// and one that operates on 1 block.
