Resumen:
The white noise is present in nature and impacts the communication systems, that
is why it is important to emulate its effect for use in today’s systems that reach even
higher operating frequencies. Thus, this work aims to obtain a high performance
hardware implementation that generates gaussian values with accuracy of 9.15 .
The method used in this work was already developed by Guangxi Liu, but here there
are architectural and mathematical modifications. To achieve this goal, the ICDF
(Inverse Cumulative Density Function) technique was used, in which second-order
interpolations were made to convert uniformly distributed values to Gaussian values.
The mathematical analysis was developed in order to calculate the new coefficients
to be used in the interpolation, which have fewer bits than the original ones. The
hardware implementation was done with HDL (Hardware Description Language),
in SystemVerilog, using the technique of pipeline to apply high frequencies of clock,
then logic synthesis was made in 28 nm technology - SMIC, analyzing the area,
power consumption, timing and gate level simulation, and analysis of mathematical
results to verify the reliability of the generated data.
