Re: [oc] pseudo random generator verilog code source



I wrote up a webpage about using LSFRs (Linear Shift
Feedback Registers) for pseudo-random number
generation during time off work, maybe it will help:

http://vnsnes.freeshell.org/lfsr/index.html

A link to an old Altera LFSR core is at the bottom of
the page.

Hope this helps.
