# AES for PA-RISC.

#

# June 2009.

#

# The module is mechanical transliteration of aes-sparcv9.pl, but with

# a twist: S-boxes are compressed even further down to 1K+256B. On

# PA-7100LC performance is ~40% better than gcc 3.2 generated code and

# is about 33 cycles per byte processed with 128-bit key. Newer CPUs

# perform at 16 cycles per byte. It's not faster than code generated

# by vendor compiler, but recall that it has compressed S-boxes, which

# requires extra processing.
