seed

mars_kiss64_seed_t seed = {123456789, 234567891, 345678912, 456789123}

static

YUCK copy and pasted RNG to allow inlining and also to avoid horrific executable bloat.

Algorithm is the KISS algorithm due to Marsaglia and Zaman. (Fortunately, we don't do cryptography on SpiNNaker.)

Returns

random number, uniformly distributed over range 0 .. 2^{STDP_FIXED_POINT_ONE}
