pesudo random

Hi,

I need a 32-bit pesudo random number generator?

thx

1 to 32 random number generator circuit

Here it is !

This is a verilog model of a 32-it PRN generator which generates the max. number of random numbers.


module prn_gen32
(
reset,
clk,
init_val,
prn
);

input reset;
input clk;
input [31:0] init_val;
output prn;
wire prn;

reg [31:0] G;

always @(posedge clk)
if (reset)
G <= init_val;
else
G <= {(G[0] ^ G[2] ^ G[6] ^ G[7]), G[31:1]};

assign prn = G[0];
endmodule

fpga prn generator

Actually, you can serach the polynomial
in google, for the different pseudo number generator.

For different length, there is different polynmial
for it... And for different application, there is also
different generator, I think your spec already provide this, you just implement it.

Hi,
I need also a pesudo random number generator but with less number 0f bits (only 4 or 8 bits)
and I need to implement it with discrete componenets (no FPGA), can any one give me good circuit (preferable to be with PCB layout) that helps me to do that?

thanks alot in advance,
ahmad,

First, thank you for help
I didn't find a random number gen. circuit in your links
but, i need a circuit, nither a C++ Program, nor a FPGA based design.
Thanks again,
Ahmad,

if you see fig.3 in
h**p://www.techonline.com/community/ed_resource/feature_article/38012
you will find a circuit.

Also pg. 730, section 8.5.8 of Wakerly's Digital Design
there is another circuit.

ARROGANCE is a bad thing...!!!!!!Do your home work....
