提出了一種以S3C2440A為核心處理器的銀行評(píng)價(jià)器的設(shè)計(jì)方案，并結(jié)合XILINX公司的XL95144XL型CPLD，輔助S3C2440A，實(shí)現(xiàn)該銀行評(píng)價(jià)器的各部分功能以及系統(tǒng)信號(hào)之間的相互協(xié)調(diào)。該評(píng)價(jià)器在系統(tǒng)設(shè)計(jì)上采用液晶屏顯示，代替了以往簡(jiǎn)單的數(shù)碼管電路的顯示模式，在視覺(jué)上給人以全新的享受。同時(shí)，評(píng)價(jià)器增加了新的網(wǎng)絡(luò)供電方式，只要將評(píng)價(jià)器連接上網(wǎng)絡(luò)就可以正常工作，方便了客戶的使用。總之，此款銀行評(píng)價(jià)器采用了嵌入式系統(tǒng)的設(shè)計(jì)方案，大大豐富了系統(tǒng)功能，實(shí)現(xiàn)一個(gè)銀行評(píng)價(jià)器設(shè)計(jì)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.
