# AES-NI-CTR+GHASH stitch.

|
|
# OpenSSL GCM implementation is organized in such way that its
|
|
# performance is rather close to the sum of its streamed components,
|
|
# in the context parallelized AES-NI CTR and modulo-scheduled
|
|
# PCLMULQDQ-enabled GHASH. Unfortunately, as no stitch implementation
|
|
# was observed to perform significantly better than the sum of the
|
|
# components on contemporary CPUs, the effort was deemed impossible to
|
|
# justify. This module is based on combination of Intel submissions,
|
|
# [1] and [2], with MOVBE twist suggested by Ilya Albrekht and Max
|
|
# Locktyukhin of Intel Corp. who verified that it reduces shuffles
|
|
# pressure with notable relative improvement, achieving 1.0 cycle per
|
|
# byte processed with 128-bit key on Haswell processor, 0.74 - on
|
|
# Broadwell, 0.63 - on Skylake... [Mentioned results are raw profiled
|
|
# measurements for favourable packet size, one divisible by 96.
|
|
# Applications using the EVP interface will observe a few percent
|
|
# worse performance.]
|
|
#
|
|
# Knights Landing processes 1 byte in 1.25 cycles (measured with EVP).
