基于SoPC的嵌入式文字识别系统设计

设计了一种基于SoPC的嵌入式文字识别系统。在FPGA平台下,基于SoPC框架搭建软硬件协同系统,设计硬件电路完成文字图像的采集和预处理,嵌入Linux系统,使用其下的识别引擎完成文字图像的识别。采用Altera公司的SoPC builder构建系统框架,Quartus II完成硬件电路的设计,在宿主机Linux环境下完成了软件部分的交叉编译并嵌入到FPGA平台。整体设计在DE2-70开发板上完成了系统验证。

An SoPC design of character recognition system

This paper introduces a design of an embedded character recognition system based on SoPC,which is using hardware circuit to complete image collection and processing while using character recognition engine under Linux to implement character recognition on FPGA platform,and setting up the hardware and software co-working system based on SoPC.The whole design uses SoPC builder which is provided by Altera to complete SoPC design,and uses Quartus II to finish hardware development,and finishes software part by using cross-compile in host Linux environment which is embedded into FPGA.At last,softeware and hardware is downloaded in Altera DE2-70 development board to finish the fuction validation of the whole system.
