fifo input 中文意思是什麼
fifo input
解釋
先進先出輸入-
Caused by the strict fifo service rule, hol cell block is the very disadvantage of the input - queued atm switches. to solve the problem, two things should be considered, that is the selection of scheduling strategy " and the decision of switch structure
輸入排隊atm交換的最大問題是它的隊首（ hol ）阻塞，它是由於嚴格的fifo服務規則所引起的，在對該問題的解決上主要涉及兩個方面：調度策略的選擇和交換結構的確定。 -
Fifo first input first output
先入先出隊列 -
In order to apply the system ' s real - time, this design uses a kind of fifo data memorizer, idt7204 which need not address and the data ' s input and output are independent
為實現系統的實時性，本系統採用一種先進先出的數據存儲器id竹204 ，無須地址線，且數據的輸入和輸出是獨立分開的。 -
Software design includes many aspects, such as design of interface, interrupt and clock control, monitoring, etc. sampling and accessing quickly data of chromatogram peak is an important tache to ensure analytic and real time performance of chromatograph, fifo make high - speed input and output of a / d sampling data possible, and expended memory, instead of disk, save a great deal of peak data and process parameter
硬體系統由cpu 、 a / d 、 d / a 、顯示驅動、實時鐘五個模塊組成，軟體設計包括譜峰數據的高速採集和存取、人機界面的設計、中斷和實時鐘控制、監測控制等方面的工作。譜峰數據的高速採集和快速存取是保證工業色譜儀分析性能和實時性的重要環節，採用了fifo存儲器技術實現a / d采樣數據的高速輸入輸出，使用擴展內存代替硬盤存貯過程參數和海量的譜峰數據。 -
Especially it allows various types of interruptions of external digital input, timer output and a / d conversion, each type of interruption has its own role in the signal measurement or in exact pace control, its fifo buffer function makes it possible to work at the sampling rate of 200k samples per second without carrying over - burden interruption rate, its latch type external interrupt request along with its high frequency clock makes a precise locating of pulse edges possible
該控制系統在工作過程中，有多種產生於不同部件的信號需要檢測，其中有模擬輸入信號十三路，數字輸入信號三路，通過數據採集和信號分析，判斷該控制系統工作是否正常。結合系統檢測的具體要求，本論文從硬體設計和軟體設計兩個方面，實現了數據採集系統的硬體介面電路和軟體演算法。
