HI friends ,

I need information about pseudo random number generator to implement it in hardware.

Thanks and Regards,

Look for LFSR techniques, fairly well known approach to do this. Do a google and you can even find HDL code on the net.

The random generator is just a LFSR in circuit, the theory is CRC, primitive poninomial division.
 

HI friends,

i am looking into LFSR technique .my requirement is i need to generate a random number of width 2048 bits.


The crc will be max of 32 bits right.so i am confused .

Thanks and Regards,
Srilekha
 

One correction. CRC need not be 32 bits. it depends on the maximum power of the polynomial used to generate the checksum. So, assuming that you have a polynomial of power 32, a simple question comes to my mind

Are you going to send this 2048 bits in serial or in parallel or in staggered fashion (like 32 bits in each clock till all 2048 bits are generated)?
 

Better use scrambler i.e
x7 + x4 + 1
 

i need to generate a random number of 1024 bits width .is anyone having an idea of random number generation using ANSI X 9.31

Thanks and Regards,
Srilekha
 

x7 + x4 + 1


I need to know on what basis we have chosen this polinomial and Why?
