do_recursion()

void do_recursion ( w128_t * r, w128_t * a, w128_t * b, w128_t * c, w128_t * d )

inlinestatic

This function represents the recursion formula.

Parameters

r	output
a	a 128-bit part of the internal state array
b	a 128-bit part of the internal state array
c	a 128-bit part of the internal state array
d	a 128-bit part of the internal state array

Here is the call graph for this function:

lshift128()

void lshift128 ( w128_t * out, w128_t const * in, int shift )

inlinestatic

This function simulates SIMD 128-bit left shift by the standard C. The 128-bit integer given in in is shifted by (shift * 8) bits. This function simulates the LITTLE ENDIAN SIMD.

Parameters

out	the output of this function
in	the 128-bit data to be shifted
shift	the shift value

Here is the caller graph for this function:

rshift128()

void rshift128 ( w128_t * out, w128_t const * in, int shift )

inlinestatic

This function simulates SIMD 128-bit right shift by the standard C. The 128-bit integer given in in is shifted by (shift * 8) bits. This function simulates the LITTLE ENDIAN SIMD.

Parameters

out	the output of this function
in	the 128-bit data to be shifted
shift	the shift value
