It is designed for embedded applications with the following features : separate instruction and data caches ( harvard architecture ), 5 - stage pipeline, hardware multiplier and divider, interrupt controller, 16 - bit i / o port and a flexible memory controller. new modules can easily be added using the on - chip amba ahb / apb buses. it has flexible peripheral interfaces, so can be used as an independent processor in the board - level application or as a core in the asic design
它遵照ieee - 1745 ( sparcv8 )的結構,針對嵌入式應用具有以下特點:採用分離的指令和數據cache (哈佛結構) ,五級流水,硬體乘法器和除法器,中斷控制器, 16位的i / o埠和靈活的內存控制器,具有較強的異常處理功能,新模塊可以輕松的通過片上的ambaahb / apb總線添加。To testify the correctness of the system ' s design, three routines are designed in this thesis : 1. clock tick test ; 2. task management directives test ; 3. cpu usage test
為了驗證系統設計的正確性,論文設計了3個驗證常式,它們是:一、時鐘滴答測試;二、基於單處理器的任務管理指令測試;三、 cpu利用率測試。When an emulator supporting user - mode emulation encounters a system call instruction, on the other hand, it does not transfer control to the emulated exception handler ; instead it interprets the system call itself
另一方面,當一個支持用戶模式模擬的模擬器碰到一個系統調用指令時,它並不是把控制轉交給模擬的異常處理程序,相反,它會自己解釋該系統調用。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 checking process of embedded processor, random instruction testing plays an important role to reduce the design period of processor
在嵌入式處理器的驗證過程中,隨機指令測試起到了非常重要的作用,利用它,可以縮短處理器設計周期。Although gpu has a very high computing speed, algorithms implemented in cpu cannot be put to execute in gpu directly because of the discrepancy in instruction execution manner of the two. gpu ' s architecture is a high parallel simd instruction set system. to reimplement algorithms insufficient to run on cpu with programmable graphics hardware, it has to reconsider the data structures and procedures to implement them to make full use of the
雖然gpu具有非常高的計算速度,但並不能將以前在cpu中實現的演算法直接放到gpu中來執行,這是因為gpu的指令執行方式和cpu不一樣, gpu的體系結構是一種高度并行的單指令多數據( simd )指令執行體系,所以要在可編程圖形硬體上實現在cpu中效率不高的演算法,就需要重新制定演算法實現的數據結構和步驟,以充分利用gpu并行處理體系結構帶來的性能優勢。It contains the code ' s character of sinumerik 810d / 840d system and fanuco - mc system on hole machining constant cycle. analysis the cutter location file ' s structure of mastercam system. studies the machine tool ' s specifie d files " design and making methods
本文研究、比較了常見cad / cam系統的刀位原文件格式,總結了sinumerik810d / 840d系統基本指令代碼的特點,詳細分析了sinumerik810d / 840d系統和fanuc0 - mc系統在孔加工固定循環上的異同;剖析了mastercam系統的刀位原文件結構,研究了mastercam後置處理系統的機床特性文件的設計和定製方法。Note that embedded microprocessors are frequently implemented without direct hardware support for the powerpc floating - point instruction set, or only provide an interface to attach floating - point hardware
注意,嵌入式微處理器實現時經常不提供對浮點指令集的直接硬體支持,或者只是提供一個附加浮點硬體的介面。分享友人
