摘要
阐述了采用EP9312来构造银行税务类嵌入式系统的理由,将EP9312与其它嵌入式处理器进行了比较。根据EP9312的特点和系统需求,提出了一种基于EP9312的嵌入式系统硬件设计方案。介绍了系统的技术指标及其所使用的Super I/O、PHY、接口电平转换器、Flash、SDRAM、Boot-loader等各组成部分。该系统主要应用于高端打印机、计算机终端和高端收款机等产品。
The hardware design of embedded system with EP9312 according to its characteristic and me system requirement is introduced, after comparing EP9312 with other processors. The reason to choose EP9312 is also given. The technical specification of the system and the Super I/O, PHY, electric level conversion, Flash, SDRAM, bootloader etc are also introduced. This system will be mainly used to design the products of terminal, printer, cash register and so on.
