Before the connectting between moden and other equipments, it works at the cammand mode, the cammand that is send to moden is used to set or manipulate the mode, after the connectting between moden and other equipments, it works at connectting mode, at that time, the cammand send from the computer is send to another computer which will pass the moden and telephone line. the moden control cammand is called " at " cammand, all the control manipulation is realized by sending the ascii character to moden, after the moden received the " at " cammand, it firstly judges the cammand, secondly, it analyses and executes the cammand, finnally, it executes a response by sending back a ascii character, during the deseign of below - computer, we introduce in detail the deseign of system hardware and system software, below - computer system hardware and system software, below - computer is made up of microchip collecting and controlling system, which finish the strobe and water level data collection, display and disposal, deal with the communication with the above - computer, the microchip is the centre of data dealing with, the peripheral equipments are made up of data collecttion module, control cammand input module, display module, execute output module, and long - distance communication module
在moden控制軟體的設計中,詳細敘述了moden正常工作時的幾個重要函數:初始化函數、撥號處理函數、應答處理函數、掛機處理函數,設計並調試了四個函數的通信程序,數據機工作時存在兩種模式,命令模式與連線模式,命令模式是針對功能設置的模式,連線模式是數據傳輸的模式。當數據機未與其他設備連接時,其處于命令模式,這時候下達給數據機的指令是作為數據機本身設置或操作用的;當數據機已經與其他設備連接時,其處于連線模式,所有在此時由計算機送至數據機的信息都將經由電話線傳送到另一部計算機上。專門使用於控制數據機的指令集被稱為「 at指令集」 ,對moden的所有操作(如撥號、應答、掛機等)都可以通過給moden發送ascii字元串來實現, moden在收到at命令后,先對命令進行判斷,接著分析和執行命令緩沖區中的命令,最後以自身的ascii字元對命令作出響應。In the digital ultrasonic flaw detectors, backward - wave signal is sampled and changed through the highspeed a / d converter, and we ' ll get a large number of datas. because datas are not all be used to draw testing curve, they must be compacted. lt is necessary to compress so much datas, so data - compaction instrument must be designed and used. here introduces the principle of data - compaction instrument, and designs a exclusive instrument using isp which may change compression point and automatically provide 1024 consecutive addresses of outside data storage unit
在數字化超聲波探傷中,回波信號經高速a d采樣變換后,會得到大量的採集數據。但在探傷曲線的描繪中並不是用到所有數據,因此要對這些數據進行壓縮處理,這就需要用到數據壓縮器,這里介紹了一種應用在線可編程技術及器件實現對大量采樣數據進行快速壓縮的方法,並設計了一種新型的專用isp數據壓縮器,該壓縮器具有壓縮點數可調,可自動提供1024個連續的外部數據存儲單元的地址等特點。It ’ s a 16 / 32bits risc cpu based on arm920t ip core, which is highly integrated and powerful. this cpu has a lot of peripheral interfaces and i / o ports, which will facilitate our system design. the asic ime6400 is a system level chip which supports the multi - channel mepg4 video / audio compression. in our design, it ’ s served as an video compression oriented co - processor working under the control of s3c2410x. s3c2410x will do the job of importing the other vehicle traveling data such as analog and switch signals
在筆者設計的系統中, ime6400作為專門進行數字視頻信號壓縮的協處理器,與s3c2410x協同工作,完成視頻信號的獲取,壓縮等工作;同時利用晶元的片內外設(如ad轉換器和i / o口) ,完成汽車行駛過程中開關量和模擬量的獲取和存儲,以滿足一個記錄儀的基本功能需求。The system adopts an advanced specific speech compression chip based on ambe algorithm. it can achieve high compression rate at 4 kb / s. the system first performs a / d conversion on analog speech input to obtain pcm signal and the pcm signal was encoded by the main compression chip
它採用了比較先進的基於ambe演算法的專用語音壓縮編/解碼晶元,壓縮率高,可以將數字語音信號碼率壓縮至4kb / s ,且編碼速率可通過修改控製程序選擇。In the paper, the followings are the pivotal points : 1 the realization of data transfer through pci bus of computer and hpi interface of dsp 2 the realization of modulation with dsp based on dds 3 the realization of code with computer 4 design bootloader of dsp 5 program pci interface board driver the significance of the paper is that it adopts the advanced digital technology to realize data transfer between dsp and computer and complete the modulation through dsp
5pci介面卡驅動程序的設計。本論文研究的意義在於採用了當前通信領域中先進的數字技術來實現dsp與計算機的數據交換,並根據dds原理實現數據的調制輸出,而不需要專門的調制晶元。本設計所實現的計算機同dsp的數據交換、利用dds實現數據調制以及自己設計的boot程序都是比較新穎的技術,為dsp在該領域的應用提供了一個成熟的範例。分享友人
