class xf::fintech::XoShiRo128Plus¶

#include "xoshiro128.hpp"

Overview¶

XoShiRo128Plus is a 32-bit all-purpose, rock-solid generator.

Methods¶

XoShiRo128Plus¶

XoShiRo128Plus ()

default constructor

init¶

void init (unsigned int* seedIn)

init initialize seeds

Parameters:

seedIn

input seeds

next¶

ap_uint <W> next (void)

each call of next() generate a pseudorandom number

Returns:

return a pseudorandom number

jump¶

void jump (void)

the jump function is equivalent to 2^64 calls to next() ; it can be used to generate 2^64 non-overlapping subsequences for parallel computations.

long_jump¶

void long_jump (void)

the long-jump function is equivalent to 2^96 calls to next() ; it can be used to generate 2^32 starting points, from each of which jump() will generate 2^32 non-overlapping subsequences for parallel distributed computations.
