Method for multicore implementation of spike neuron based on Nios Ⅱ

选定Izhikevich脉冲神经元模型作为计算单元,讨论了4种NiosⅡ处理器的通信方法.针对Izhikevich神经元的特点,经过实验比较,采用其中2种NiosⅡ多核通信技术相结合的方式实现脉冲神经元并行计算结构.该结构能很好地实现Izhikevich神经元的功能,并且能充分体现脉冲神经网络并行计算的特点.

The third generation neural network which has better biological characteristics and named spiking neural network is a hot research topic in recent years.Firstly,Izhikevich neuron mode is used as the calculating unit.Secondly,communication methods of four Nios Ⅱ processors are discussed.Finally,two kinds of NiosⅡ multicore technology are combined to realize the structure of the parallel computation of neurons after experimental comparison according to the characteristics of Izhikevich neurons.The structure can achieve the function of Izhikevich neuron,and can fully reflect the characteristics of the parallel computing of the spiking neural network after testing.
