/* Yet another implementation of MixBytes.
|
||||
This time we use the formulae (3) from the paper "Byte Slicing Groestl".
|
||||
Input: a0, ..., a7
|
||||
Output: b0, ..., b7 = MixBytes(a0,...,a7).
|
||||
but we use the relations:
|
||||
t_i = a_i + a_{i+3}
|
||||
x_i = t_i + t_{i+3}
|
||||
y_i = t_i + t+{i+2} + a_{i+6}
|
||||
z_i = 2*x_i
|
||||
w_i = z_i + y_{i+4}
|
||||
v_i = 2*w_i
|
||||
b_i = v_{i+3} + y_{i+4}
|
||||
We keep building b_i in registers xmm8..xmm15 by first building y_{i+4} there
|
||||
and then adding v_i computed in the meantime in registers xmm0..xmm7.
|
||||
We almost fit into 16 registers, need only 3 spills to memory.
|
||||
This implementation costs 7.7 c/b giving total speed on SNB: 10.7c/b.
