This paper analyzes 2 critical problems in FPGA-based implementation of SOM neural network algorithm: parallelizability and finiteword-lengtheffect.
分析了SOM神经网络算法在FPGA实现过程中要考虑的2个主要问题:并行性和有限字长效应。

Because word-length of register is finite. It is necessary to consider the question about the finiteword-lengtheffect during the devising digit filter.
由于寄存器的字长是有限的,因此要在数字滤波器的设计过程中考虑各种有限字长效应问题。

A new analysis method based on theoretical statistic models was proposed to analyze finiteword-lengtheffect, instead of the complicated and time-consuming sample statistics process.
