Retro Programming: 16-Bit Xorshift Pseudorandom Numbers in Z80 Assembly

Xorshift is a simple, fast pseudorandom number generator developed by George Marsaglia. The generator combines three xorshift operations where a number is exclusive-ored with a shifted copy of itself: /* 16-bit xorshift PRNG */ unsigned xs = 1; unsigned xorshift( ) { xs ^= xs << 7; xs ^= xs >> 9; xs ^= xs << 8; return xs; } There are 60 shift triplets with the maximum period 216-1. Four triplets p
