Optimization of FPGA Architecture for Uniform Random Number Generator Using LUT-SR Family

Rita Rawate | M. V. Vyawahare

Abstract: Field-Programmable Gate Arrays (FPGAs) are widely used to implement logic without going through an expensive fabrication process. Field-programmable gate array optimized random number generators (RNGs) are more resource-efficient than software-optimized RNGs because they can take advantage of bitwise operations and FPGA-specific features. The software community has de- veloped a number of high-quality, long period Random Number Generators (RNGs), some of which have been adapted for use in FPGAs. However, these generators were designed to meet the needs of word-level instruction processors, and so are less efficient when mapped to the bit-level operations available in FPGAs. This paper describes a type of FPGA RNG called a LUT-SR RNG, which takes advantage of bitwise XOR operations and the ability to turn lookup tables (LUTs) into shift registers of varying lengths. This provides a good resourcequality balance compared to previous FPGA-optimized generators. This paper deals with optimization of FPGA and simulations is done in VHDL.
