Resumo:
This dissertation describes the design, the developing and the implementation in
hardware of a new architecture of multiplying finite fields based upon the Mastrovito
multiplier. Such architecture utilizes linear threshold ports as basic processing elements,
which are the basic elements of a discrete neural network. The discrete neural networks
implemented with threshold ports allow reduce the complexity of the circuits when they
are compared to implementations of traditional logics (AND, OR and NOT ports). For
this reason, extending and implementing linear threshold ports in the arithmetic’s of the
finite fields becomes an attractive activity. Thus, with the objective of proving the
efficiency of such ports as basic units of processing of the multiplying architecture in
GF (2n), that it has been designed, in the hardware description language Verilog, a
GF (28)multiplier utilizing the linear threshold ports. Several levees of abstraction
have been developed. The FPGA (Field-Programmable Gate Array) Quartus II® tool
and the developing Altera® hardware EP2C35F672C6 have been utilized. The results of
the development which are presented indicate the practical functioning of the new
architecture proposed by the GF (28) multiplier. However, its efficiency in terms of
time processing and counting of ports is under what would be expected. From the
results the multiplication operation in finite fields was observed with an accuracy rate of
90%.
