| +# AES for ARMv4 |
| + |
| +# January 2007. |
| +# |
| +# Code uses single 1K S-box and is >2 times faster than code generated |
| +# by gcc-3.4.1. This is thanks to unique feature of ARMv4 ISA, which |
| +# allows to merge logical or arithmetic operation with shift or rotate |
| +# in one instruction and emit combined result every cycle. The module |
| +# is endian-neutral. The performance is ~42 cycles/byte for 128-bit |
| +# key. |
| + |
| +# May 2007. |
| +# |
| +# AES_set_[en|de]crypt_key is added. |

| +# Montgomery multiplication for ARMv4. |
| +# |
| +# Performance improvement naturally varies among CPU implementations |
| +# and compilers. The code was observed to provide +65-35% improvement |
| +# [depending on key length, less for longer keys] on ARM920T, and |
| +# +115-80% on Intel IXP425. This is compared to pre-bn_mul_mont code |
| +# base and compiler generated code with in-lined umull and even umlal |
| +# instructions. The latter means that this code didn't really have an |
| +# "advantage" of utilizing some "secret" instruction. |
| +# |
| +# The code is interoperable with Thumb ISA and is rather compact, less |
| +# than 1/2KB. Windows CE port would be trivial, as it's exclusively |
| +# about decorations, ABI and instruction syntax are identical. |

| +# thumb = same as 'small' but in Thumb instructions[**] and |
| +# with recurring code in two private functions; |
| +# small = detached Xload/update, loops are folded; |
| +# compact = detached Xload/update, 5x unroll; |
| +# large = interleaved Xload/update, 5x unroll; |
| +# full unroll = interleaved Xload/update, full unroll, estimated[!]; |
| +# |
| +# [*] Manually counted instructions in "grand" loop body. Measured |
| +# performance is affected by prologue and epilogue overhead, |
| +# i-cache availability, branch penalties, etc. |
| +# [**] While each Thumb instruction is twice smaller, they are not as |
| +# diverse as ARM ones: e.g., there are only two arithmetic |
| +# instructions with 3 arguments, no [fixed] rotate, addressing |
| +# modes are limited. As result it takes more instructions to do |
| +# the same job in Thumb, therefore the code is never twice as |

| +# SHA512 block procedure for ARMv4. September 2007. |
| + |
| +# This code is ~4.5 (four and a half) times faster than code generated |
| +# by gcc 3.4 and it spends ~72 clock cycles per byte. |

| +# Byte order [in]dependence. ========================================= |
| +# |
| +# Caller is expected to maintain specific *dword* order in h[0-7], |
| +# namely with most significant dword at *lower* address, which is |
| +# reflected in below two parameters. *Byte* order within these dwords |
| +# in turn is whatever *native* byte order on current platform. |
