Hi All, I want to generate a true random number in Actel ProAsic3 FPGA development board which operates at 48 MHz. I tried to implement it using ring oscillators (RO) and used the system clock i.e. 48 MHz as sampling frequency. As the sampling period is around 48 MHz => 21 ns, the RO period should at least be double the sampling frequency, i.e.
I am trying to generate TRUE random numbers on Kintex-7. I am following the paper published by Xilinx, where a ring oscillator is used for random number generation and LHCA has been used as a scrambler. BUT, whenever I capture 11 Mega bytes of data (True random numbers) and pass them (...)
Hi, look for "Pseudo random number generator" using shift registers with feedback. Ive used it with AVRs and assembler, but not on PICs. Klaus
Hi All I have a problem to NOISE Analysis in HSPICE 2013. I am working on True random number generator based on Metastability. I have to simulate a circuit in HSPICE and I have to analysis the Noise. Can any one to help me?
Hello, I design an inductorless Chua circuit based on the design found in and by replacing the LMC6482AIN opamp by TL081 The circuit works but when I tried to connect the output with comparator (open loop TL0821 opamp or LM311) the output signal was vanished. I tried to couple the two
Hi Guys. Recently, I'm getting interested in the PRN generator Using Linear Feedback Shifting Register(LFSR). If Low Power Performance is desired, which Logic Type and clock strategy are preferred.
I am using a Bernoulii Binary generator to generate my data signal for a Direct sequence spread spectrum model I am designing on SIMULINK. The specifications of the generator block is as follows : Probability of zero : 0.5 Initial seed : 61 ( random number ) sample time : 0.6 Frame based outputs Samples per frame : (...)
@Trickedeasy Whether the seed are initialised to a particular number or left uninitialised, for both cases, same sequence of random number are generated I think this is not true for a LFSR generator. probably you could not load your LFSR correctly or mot simulating enough time. I need random seed values (...)
Hi all, Can any body plz give me code to generate 4 digit random number which should not be repeated if appear once until all 9998 combinations. Code should run in KEIL for ARM. I wrote one with 'randomize ()' and random function which is giving an error in KEIL. Plz guide.
The Monte Carlo process isn't truly random. It uses a pseudo random number generator based on a seed value. If you don't change the seed you will get identical results from two groups of Monte Carlo runs. I have never experimented with netlist order but it seems reasonable that changing that will change the results. The (...)
do u have the matlab code for gaussian noise generation without wgn or awgn functions.....i would like to generate statistical noise and i think the above functions are related to random noise....that is why i asked for a code other than the functions... Thank you...
I am trying to build a simple transmitter and receiver in simulink. Output of random number generator multiplied with PN generator. Then, after bpsk modulation and raised cosine pulse shaping it is fed to awgn channel. I need to know the parameters for this design and ways to reduce BER.
To clarify, the upper two bits as the feedback taps only works for a few lengths. Simply try a 3b lfsr, 4b lfsr, and 5b lfsr. The 3b/4b will work, but the 5b lfsr will have cycles of different length based on the initial value of the state register. If you want to use two taps, try the 15b lfsr as the two msb's are correct for a sequence of leng
random number (RAND), which is a frequently changing 128-bit random or pseudo-random number that is made by the Bluetooth device software itself. Common input for key generation. All Bluetooth devices have this random number generator. Bluetooth (...)
I made a true random number generator from a 74HC595 shift register and a 74HC04 hex inverter. With the addition of a 4538 precision monostable and a few passive components, I had a randomly twirling laser cat
Possibly, but the number may be cyclic because the timer will update at a regular rate and will always have the same start value. In other words, you may get something which looks random but gives the same pattern sequence after each processor reset. If you are finding a truly random sequence I would suspect it is because 'i' and 'start' (...)
You've done everything and asking for how to do it !!! you need to generate 8-bit pseudo random generator and want to show that combination through 8 LEDs , Right ? Now you've already done with 8 bit pseudo random number generator and need an assemble code to display as well as to store on flash !!! Here (...)
Im trying to make 2 random number simultaneously, using timer 0. but im not sure how to. i also heard that timer 2 can be used as well. can any 1 help me with a sample code. this is my code: #include #include void ISR (void); char i,start,end; #pragma code L_vector=0x18 void L_vector(void){ _asm goto I
I have a problem with the random number generator function with MPLAB c programming. We use rand() to generate 2 numbers, but the 1st number is generated randomly in odd sequence and the other number is generated randomly in even sequence. The (...)
Hi write an LFST code generator(u can find on the net) then treat its output as a floating point number between 0 and 1 then multiply it by a number that you want to have jitter for example you want to have 0 to 10 percent jitter so multply by 10 then you will have a random number between 0 and ten. then (...)
