摘　　要：汉盲翻译是一种将中文文本自动翻译为对应的盲文数据的过程.在嵌入式环境下,汉盲翻译的速度较慢,难以达到复杂环境下的实时性需求.为此设计出专用的汉盲翻译IP核,通过实现逆向最大匹配分词算法、汉盲转换,最终得到准确的盲文数据.为了验证设计的合理性,以Cortex-M3为微处理器构建SoC,搭载串口、LCD驱动和汉盲翻译IP核,并使用FPGA实验平台进行功能验证和性能测试.测试结果表明,该SoC可准确进行汉盲翻译,翻译速度达5 079.37 B/s.Chinese-braille translation refers to the process of automatically translating a Chinese text into corresponding braille data.In an embedded environment,the speed of Chinese-Braille translation is relatively slow,and it is difficult to meet the real-time requirements in complex environments.Therefore,an IP core for dedicated Chinese-braille translation is designed,which can achieve accurate braille data by implementing a reverse maximum matching segmentation algorithm and Chinese-braille conversion.In order to verify the rationality of the design,the SoC is constructed with Cortex-M3 as the microprocessor,which is equipped with serial ports,LCD drivers,and an IP core for Chinese-braille translation.Functional verification and performance testing are carried out by using FPGA experimental platform.The test results show that the SoC can accurately perform Chinese-braille translation at a speed of 5079.37 B/s.
