# AES for MIPS
|
||
|
||
# October 2010
|
||
#
|
||
# Code uses 1K[+256B] S-box and on single-issue core [such as R5000]
|
||
# spends ~68 cycles per byte processed with 128-bit key. This is ~16%
|
||
# faster than gcc-generated code, which is not very impressive. But
|
||
# recall that compressed S-box requires extra processing, namely
|
||
# additional rotations. Rotations are implemented with lwl/lwr pairs,
|
||
# which is normally used for loading unaligned data. Another cool
|
||
# thing about this module is its endian neutrality, which means that
|
||
# it processes data without ever changing byte order...
|
||
|
||
# September 2012
|
||
#
|
||
# Add MIPS32R2 (~10% less instructions) and SmartMIPS ASE (further
|
||
# ~25% less instructions) code. Note that there is no run-time switch,
|
||
# instead, code path is chosen upon pre-process time, pass -mips32r2
|
||
# or/and -msmartmips.

# There is a number of MIPS ABI in use, O32 and N32/64 are most
|
||
# widely used. Then there is a new contender: NUBI. It appears that if
|
||
# one picks the latter, it's possible to arrange code in ABI neutral
|
||
# manner. Therefore let's stick to NUBI register layout:
|
||
#
|
||
($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
|
||
($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
|
||
($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
|
||
($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
|
||
#
|
||
# The return value is placed in $a0. Following coding rules facilitate
|
||
# interoperability:
|
||
#
|
||
# - never ever touch $tp, "thread pointer", former $gp;
|
||
# - copy return value to $t0, former $v0 [or to $a0 if you're adapting
|
||
# old code];
|
||
# - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
|
||
#
|
||
# For reference here is register layout for N32/64 MIPS ABIs:
|
||
#
|
||
# ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
|
||
# ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
|
||
# ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
|
||
# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
