Implementation of Fpga-based Pseudo-random Words Generator

A hardware implementation of pseudo-random bit generator based on FPGA chips, which use the principle of reconfigurability that allows the modernization of their algorithms and on-line replacement of the internal structure (reconfiguration) in the process of functioning have been considered in the paper. Available DSP blocks embedded into the structure of FPGA chips allow efficient hardware implementation of the pseudorandom bit generator through the implementation of the basic operations of multiplication with accumulation on the gate level.


In the article, the basic VHDL-AMS models of MEMS-based capacitive accelerometers were developed. The models were designed for two basic types of capacitive accelerometers, namely lamellar and counter-pivotal. The developed models allow us to determine the source of electrical capacitive accelerometers depending on the incoming mechanical and structural parameters and were constructed for MEMS CAD at the circuit level. The circuit level of MEMS development requires an analysis of the total integrated device electric circuits.
