# 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]. Streamed
# GHASH performance was measured to be 6.67 cycles per processed byte
# on Itanium 2, which is >90% better than Microsoft compiler generated
# code. To anchor to something else sha1-ia64.pl module processes one
# byte in 5.7 cycles. On Itanium GHASH should run at ~8.5 cycles per
# byte.
# September 2010
#
# It was originally thought that it makes lesser sense to implement
# "528B" variant on Itanium 2 for following reason. Because number of
# functional units is naturally limited, it appeared impossible to
# implement "528B" loop in 4 cycles, only in 5. This would mean that
# theoretically performance improvement couldn't be more than 20%.
# But occasionally you prove yourself wrong:-) I figured out a way to
# fold couple of instructions and having freed yet another instruction
# slot by unrolling the loop... Resulting performance is 4.45 cycles
# per processed byte and 50% better than "256B" version. On original
# Itanium performance should remain the same as the "256B" version,
# i.e. ~8.5 cycles.
