提出了一种以S3C2440A为核心处理器的银行评价器的设计方案，并结合XILINX公司的XL95144XL型CPLD，辅助S3C2440A，实现该银行评价器的各部分功能以及系统信号之间的相互协调。该评价器在系统设计上采用液晶屏显示，代替了以往简单的数码管电路的显示模式，在视觉上给人以全新的享受。同时，评价器增加了新的网络供电方式，只要将评价器连接上网络就可以正常工作，方便了客户的使用。总之，此款银行评价器采用了嵌入式系统的设计方案，大大丰富了系统功能，实现一个银行评价器设计的新突破。
- Abstract:
- S3C2440A of SamSung company is the core component of the embedded system. A design of bank assessor based on S3C2440A was provided in this paper. It used XL95144XL combined with S3C2440A to realize all the functions and coordination with system signals. This bank assessor used LCD to display instead of the former simple digital display and provided a new seusuous enjoment. Meanwhile，it provided a new method of network power supply，that the bank assessor could regularly work once it connected to the network，which is convenient for customers to use. In a word，this assessor takes embedded system，enriches the system’s functions and reclizes a new breakout.
