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.

在需要實(shí)時(shí)大量輸入漢字的顯示控制處理應(yīng)用中，利用傳統(tǒng)單片機(jī)實(shí)現(xiàn)顯示控制的設(shè)計(jì)方法是較難實(shí)現(xiàn)的。帶漢字字庫(kù)的液晶模塊的使用使得小容量ROM單片機(jī)的大量漢字信息輸入與顯示成為可能。提出了針對(duì)漢字字庫(kù)編碼的二級(jí)索引拼音輸入檢索方法,介紹了以ST7920作為控制器的帶漢字字庫(kù)的液晶顯示模塊的接口方法及漢字顯示和控制原理，給出了通用計(jì)算機(jī)鍵盤(pán)在單片機(jī)中的串行接口，采用該技術(shù)可大大增強(qiáng)單片機(jī)的漢字輸入功能。為小容量ROM單片機(jī)的大批量漢字信息處理提供了一種漢字輸入解決方案。 Abstract: It is difficult to realize Chinese characters input method based on the embedded system by using the traditional design method of display control. It is possible to input and display Chinese characters based on the embedded system with the ROM of small content by using the LCD module with Chinese characters.Chinese characters input method of the quadric index recall in allusion to Chinese characters code is brought forward.The interface and the principle of Chinese characters display control based on the LCD module controlled with the ST7920 is introduced too.The serial interface of the computer keyboard in common use and the embedded system is given at the same time. It can enhance the embedded system function of Chinese characters input by using this technology, and provide a kind of Chinese characters input scheme for the embedded system with small capacity ROM.

為提升虛擬儀器傳輸速率與實(shí)時(shí)性能，擴(kuò)展監(jiān)測(cè)范圍，在VC的軟件平臺(tái)上設(shè)計(jì)了一種全功能虛擬示波器。與傳統(tǒng)虛擬示波器相比，該系統(tǒng)采用嵌入式系統(tǒng)完成信號(hào)采集，采用工業(yè)以太網(wǎng)為傳輸介質(zhì)，通過(guò)線性插值算法和多線程編程思想，實(shí)現(xiàn)波形顯示、參數(shù)計(jì)算、頻譜分析以及波形存儲(chǔ)及回放功能。實(shí)驗(yàn)結(jié)果表明，該虛擬示波器可以實(shí)現(xiàn)20 kHz采樣頻率下的波形精確顯示，達(dá)到預(yù)期的各項(xiàng)指標(biāo)。 Abstract: o enhance the transfer rate and real-time of virtual instrument performance， expand scope of monitoring， this paper uses the VCs software platform to design a fully functional virtual oscilloscope. Compared with traditional virtual oscilloscope， this system adopts the embedded system to complete the data acquisition， industrial Ethernet as the transmission medium used by the linear interpolation algorithm and multi-threaded programming ideas， namely to achieve waveform display， parameter calculation， spectrum analysis and waveform storage and playback. Experimental results show that the virtual oscilloscope can accurately display the waveform with 20kHz sampling frequency， and achieve the desired targets.
