# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL

# project. The module is, however, dual licensed under OpenSSL and

# CRYPTOGAMS licenses depending on where you obtain it. For further

# details see http://www.openssl.org/~appro/cryptogams/.

|
|
# The module implements "4-bit" GCM GHASH function and underlying
|
||
|
|
# single multiplication operation in GF(2^128). "4-bit" means that it
|
||
|
|
# uses 256 bytes per-key table [+128 bytes shared table]. Even though
|
||
|
|
# loops are aggressively modulo-scheduled in respect to references to
|
||
|
|
# Htbl and Z.hi updates for 8 cycles per byte, measured performance is
|
||
|
|
# ~12 cycles per processed byte on 21264 CPU. It seems to be a dynamic
|
||
|
|
# scheduling "glitch," because uprofile(1) indicates uniform sample
|
||
|
|
# distribution, as if all instruction bundles execute in 1.5 cycles.
|
||
|
|
# Meaning that it could have been even faster, yet 12 cycles is ~60%
|
||
|
|
# better than gcc-generated code and ~80% than code generated by vendor
|
||
|
|
# compiler.
