-# ====================================================================
-# Written by Andy Polyakov <appro@fy.chalmers.se> 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/.

-# Provided that UltraSPARC VIS instructions are pipe-lined(*) and
-# pairable(*) with IALU ones, offloading of Xupdate to the UltraSPARC
-# Graphic Unit would make it possible to achieve higher instruction-
-# level parallelism, ILP, and thus higher performance. It should be
-# explicitly noted that ILP is the keyword, and it means that this
-# code would be unsuitable for cores like UltraSPARC-Tx. The idea is
-# not really novel, Sun had VIS-powered implementation for a while.
-# Unlike Sun's implementation this one can process multiple unaligned
-# input blocks, and as such works as drop-in replacement for OpenSSL
-# sha1_block_data_order. Performance improvement was measured to be
-# 40% over pure IALU sha1-sparcv9.pl on UltraSPARC-IIi, but 12% on
-# UltraSPARC-III. See below for discussion...
-#
-# The module does not present direct interest for OpenSSL, because
-# it doesn't provide better performance on contemporary SPARCv9 CPUs,
-# UltraSPARC-Tx and SPARC64-V[II] to be specific. Those who feel they
-# absolutely must score on UltraSPARC-I-IV can simply replace
-# crypto/sha/asm/sha1-sparcv9.pl with this module.
-#
-# (*) "Pipe-lined" means that even if it takes several cycles to
-# complete, next instruction using same functional unit [but not
-# depending on the result of the current instruction] can start
-# execution without having to wait for the unit. "Pairable"
-# means that two [or more] independent instructions can be
-# issued at the very same time.

-# The numbers delimited with slash are the earliest possible dispatch
-# cycles for given instruction assuming 1 cycle latency for simple VIS
-# instructions, such as on UltraSPARC-I&II, 3 cycles latency, such as
-# on UltraSPARC-III&IV, and 2 cycles latency(*), respectively. Being
-# 2x-parallelized the procedure is "worth" 5, 8.5 or 6 ticks per SHA1
-# round. As [long as] FPU/VIS instructions are perfectly pairable with
-# IALU ones, the round timing is defined by the maximum between VIS
-# and IALU timings. The latter varies from round to round and averages
-# out at 6.25 ticks. This means that USI&II should operate at IALU
-# rate, while USIII&IV - at VIS rate. This explains why performance
-# improvement varies among processors. Well, given that pure IALU
-# sha1-sparcv9.pl module exhibits virtually uniform performance of
-# ~9.3 cycles per SHA1 round. Timings mentioned above are theoretical
-# lower limits. Real-life performance was measured to be 6.6 cycles
-# per SHA1 round on USIIi and 8.3 on USIII. The latter is lower than
-# half-round VIS timing, because there are 16 Xupdate-free rounds,
-# which "push down" average theoretical timing to 8 cycles...
-
-# (*) SPARC64-V[II] was originally believed to have 2 cycles VIS
-# latency. Well, it might have, but it doesn't have dedicated
-# VIS-unit. Instead, VIS instructions are executed by other
-# functional units, ones used here - by IALU. This doesn't
-# improve effective ILP...
-}
-
-# The reference Xupdate procedure is then "strained" over *pairs* of
-# BODY_NN_MM and kind of modulo-scheduled in respect to X[n]^=X[n+13]
-# and K_NN_MM addition. It's "running" 15 rounds ahead, which leaves
-# plenty of room to amortize for read-after-write hazard, as well as
-# to fetch and align input for the next spin. The VIS instructions are
-# scheduled for latency of 2 cycles, because there are not enough IALU
-# instructions to schedule for latency of 3, while scheduling for 1
-# would give no gain on USI&II anyway.
