Buffer device and convolution operation device and method

A buffer device comprises an input line, an input buffer unit and a remapping unit, wherein the input line is coupled to a memory and is configured to input data from the memory under a current clockpulse; the input buffer unit is coupled to the input line and is configured to buffer part of the input data under the current clock pulse so as to output the data under a subsequent clock pulse; andthe remapping unit is coupled to the input line and the input buffer unit and is configured to generate multiple pieces of remapping data according to the data on the input line and output of the input buffer unit under the current clock pulse, and the remapping data is input for convolution operation. 种缓冲装置包括输入线路、输入缓冲单元以及重新映射单元。输入线路耦接存储器，配置为在当前时钟脉冲下让数据从存储器输入；输入缓冲单元耦接输入线路，配置为在当前时钟脉冲下将部分输入的缓冲以在后续时钟脉冲将其输出；重新映射单元耦接输入线路以及输入缓冲单元，配置为在当前时钟脉冲下依据输入线路上的数据以及输入缓冲单元的输出而产生多个重新映射数据，重新映射数据是供卷积运算的输入。
