Hardware Implementation of Multi-LFSR Pseudo Random Number Generator

This paper presents the implementation of a hardware pseudo-random number generator (PRNG) using multiple linear feedback shift registers (LFSRs) for generating pseudo-random numbers and ambient electromagnetic noise for seed generation. The PRNG algorithm is deployed on a Digilent CMOD A7 field-programmable gate array (FPGA) board, producing 16-bit random numbers at a frequency of 50 kHz, which are then displayed on a 7-segment display. To facilitate the transfer of generated numbers to a laptop for further use in different applications, a dedicated high-speed UART with a baud rate of 1,152,000 is designed. The performance and effectiveness of the PRNG are evaluated in this setup.
