Random-access psuedo random number generator

摘要

A system for generating a series of psuedo random numbers so that numbers in the sequence may be randomly accessed. The system includes apparatus for scrambling the bits of a plurality of seed numbers. The pattern of bit scrambling is governed by the control number. The plurality of scrambled seed numbers are exclusive-OR'ed to produce an output number. As long as the seed numbers remain unchanged, a given control number will always produce the same psuedo random number.
