# "Teaser" Montgomery multiplication module for UltraSPARC. Why FPU?
# Because unlike integer multiplier, which simply stalls whole CPU,
# FPU is fully pipelined and can effectively emit 48 bit partial
......@@ -18,16 +20,22 @@
# USI&II cores currently exhibit uniform 2x improvement [over pre-
# bn_mul_mont codebase] for all key lengths and benchmarks. On USIII
# performance improves few percents for shorter keys and worsens few
# percents for longer keys. This's because USIII integer multiplier
# percents for longer keys. This is because USIII integer multiplier
# is >3x faster than USI&II one, which is harder to match [but see
# TODO list below]. It should also be noted that SPARC64 V features
# out-of-order execution, which *might* mean that integer multiplier
# is pipelined, which in turn *might* be impossible to match...
#
# In 32-bit context the implementation implies following additional
# limitations on input arguments:
# - num may not be less than 4;
# - num has to be even;
# - ap, bp, rp, np has to be 64-bit aligned [which is not a problem
# as long as BIGNUM.d are malloc-ated];
# Failure to meet either condition has no fatal effects, simply
# doesn't give any performance gain.
# TODO:
# - complete 32-bit adaptation (requires universal changes to
# BN_MONT_CTX and bn_mul_mont prototype, but nothing really
# unmanagable:-);
# - modulo-schedule inner loop for better performance (on in-order
# execution core such as UltraSPARC this shall result in further
# noticeable(!) improvement);
