提出了一種以S3C2440A為核心處理器的銀行評價器的設計方案,并結合XILINX公司的XL95144XL型CPLD,輔助S3C2440A,實現(xiàn)該銀行評價器的各部分功能以及系統(tǒng)信號之間的相互協(xié)調。該評價器在系統(tǒng)設計上采用液晶屏顯示,代替了以往簡單的數(shù)碼管電路的顯示模式,在視覺上給人以全新的享受。同時,評價器增加了新的網絡供電方式,只要將評價器連接上網絡就可以正常工作,方便了客戶的使用。總之,此款銀行評價器采用了嵌入式系統(tǒng)的設計方案,大大豐富了系統(tǒng)功能,實現(xiàn)一個銀行評價器設計的新突破。
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.
