利用VHDL语言实现Hopfield神经网络运算

The Implementation of the Hopfield Neural Network Operation Based on VHDL

VHDL语言作为一种硬件描述语言,其并行执行的特点适合仿真神经网络,便于神经网络的硬件实现,本文简要介绍了Hopfield神经网络算法,并用VHDL语言设计和实现了Hopfield神经网络模块。Hopfield神经网络模块可应用到加密芯片上,模拟非线性函数控制伪随机序列的输出。

VHDL language is a hardware descriptive language, whose characteristic of parallel processing suits the emulation of the neural network, and is convenient for the hardware realization of neural network. This paper introduces the arithmetic of the Hopfield neural network briefly,together with the design and realization of the Hopfield neural network module in VHDL language.The Hopfield neural network module can be applied to cipher chip,which simulates nonlinear function for controlling the output of pseudo-random stream.
