# ==================================================================== |
|
|
# 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/. |
|
|
# ==================================================================== |
|
|
|
|
|
# On PA-7100LC this module performs ~90-50% better, less for longer |
|
|
# keys, than code generated by gcc 3.2 for PA-RISC 1.1. Latter means |
|
|
# that compiler utilized xmpyu instruction to perform 32x32=64-bit |
|
|
# multiplication, which in turn means that "baseline" performance was |
|
|
# optimal in respect to instruction set capabilities. Fair comparison |
|
|
# with vendor compiler is problematic, because OpenSSL doesn't define |
|
|
# BN_LLONG [presumably] for historical reasons, which drives compiler |
|
|
# toward 4 times 16x16=32-bit multiplicatons [plus complementary |
|
|
# shifts and additions] instead. This means that you should observe |
|
|
# several times improvement over code generated by vendor compiler |
|
|
# for PA-RISC 1.1, but the "baseline" is far from optimal. The actual |
|
|
# improvement coefficient was never collected on PA-7100LC, or any |
|
|
# other 1.1 CPU, because I don't have access to such machine with |
|
|
# vendor compiler. But to give you a taste, PA-RISC 1.1 code path |
|
|
# reportedly outperformed code generated by cc +DA1.1 +O3 by factor |
|
|
# of ~5x on PA-8600. |
|
|
# |
|
|
# On PA-RISC 2.0 it has to compete with pa-risc2[W].s, which is |
|
|
# reportedly ~2x faster than vendor compiler generated code [according |
|
|
# to comment in pa-risc2[W].s]. Here comes a catch. Execution core of |
|
|
# this implementation is actually 32-bit one, in the sense that it |
|
|
# operates on 32-bit values. But pa-risc2[W].s operates on arrays of |
|
|
# 64-bit BN_LONGs... How do they interoperate then? No problem. This |
|
|
# module picks halves of 64-bit values in reverse order and pretends |
|
|
# they were 32-bit BN_LONGs. But can 32-bit core compete with "pure" |
|
|
# 64-bit code such as pa-risc2[W].s then? Well, the thing is that |
|
|
# 32x32=64-bit multiplication is the best even PA-RISC 2.0 can do, |
|
|
# i.e. there is no "wider" multiplication like on most other 64-bit |
|
|
# platforms. This means that even being effectively 32-bit, this |
|
|
# implementation performs "64-bit" computational task in same amount |
|
|
# of arithmetic operations, most notably multiplications. It requires |
|
|
# more memory references, most notably to tp[num], but this doesn't |
|
|
# seem to exhaust memory port capacity. And indeed, dedicated PA-RISC |
|
|
# 2.0 code path provides virtually same performance as pa-risc2[W].s: |
|
|
# it's ~10% better for shortest key length and ~10% worse for longest |
|
|
# one. |
|
|
# |
|
|
# In case it wasn't clear. The module has two distinct code paths: |
|
|
# PA-RISC 1.1 and PA-RISC 2.0 ones. Latter features carry-free 64-bit |
|
|
# additions and 64-bit integer loads, not to mention specific |
|
|
# instruction scheduling. In 64-bit build naturally only 2.0 code path |
|
|
# is assembled. In 32-bit application context both code paths are |
|
|
# assembled, PA-RISC 2.0 CPU is detected at run-time and proper path |
|
|
# is taken automatically. Also, in 32-bit build the module imposes |
|
|
# couple of limitations: vector lengths has to be even and vector |
|
|
# addresses has to be 64-bit aligned. Normally neither is a problem: |
|
|
# most common key lengths are even and vectors are commonly malloc-ed, |
|
|
# which ensures alignment. |
|
|
# |
|
|
# Special thanks to polarhome.com for providing HP-UX account on |
|
|
# PA-RISC 1.1 machine, and to correspondent who chose to remain |
|
|
# anonymous for testing the code on PA-RISC 2.0 machine. |
