Simple Pseudo Random Number Generator Here is a simple real mode (80386 code) PRNG with a period of (2^64)-1. It's an optimized implementation (only 5 instructions) of the Galois PRNG. I'm using it in Space Invaders: http://mikegonta.com/Space_Invaders [code] shr edx, 1 rcr eax, 1 jnc .1 xor edx, UPPER_TAPS xor eax, LOWER_TAPS .1: [/code] The complete code is here: http://mikegonta.com/Space_Invaders/blob/master/include/simple_prng.asm Mike Gonta look and see - many look but few see http://mikegonta.com
