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，實現該銀行評價器的各部分功能以及系統信號之間的相互協調。該評價器在系統設計上采用液晶屏顯示，代替了以往簡單的數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的設計方案，大大豐富了系統功能，實現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.
為提高太陽能的利用率，以ATmega8單片機為控制核心，設計了一套光電跟蹤與視日運動軌跡跟蹤互補控制的雙軸太陽跟蹤器。該跟蹤器在晴天時，利用光敏電阻采集光強判斷太陽位置,控制步進電機實現光電跟蹤；在陰天時，采集時鐘器件PCF8583的時間信息,計算當前太陽位置來實現視日運動軌跡跟蹤。實驗表明：該太陽跟蹤器能在不同天氣狀況下對太陽進行較準確地跟蹤，能量接收效率提高了30%，達到充分利用太陽能的目的。
Abstract:
To improve the utilization rate of solar energy，a kind of solar tracking controller which effectively combined the sun angle tracking and photo electric tracking based on ATmega8is designed.In the sunny days，the solar tracking con-troller determines the sun's position by using photosensitive resistances to collect light intensity and control stepper motors to achieve photo electric tracking，n cloudy days，it collects clock chip PCF8583time information to calculate the current position of the sun and achieve the sun angle tracking.Experimental results show the solar tracking controller accurately tracks the sun in different weather conditions，improves received energy efficiency by30%and reaches the purpose of full use of solar energy.
