幀參考鐘 的英文怎麼說
中文拼音 [zhèngshēnkǎozhōng]
幀參考鐘
英文
frame reference clock-
Qe1 achieve the whole synchronization by software and hardware. during the course of the initialization of the qe1 system, the chip pm4354 can accomplish the task of synchronization of bit, frame and multiframe after the chip initialization by the software. after pm4354 accomplishes the bit synchronization, qel will read the status registers of the pm4354 to get the status of each el circuit and choose recovered clock of the specified the el circuit as the external timing source of the whole htc - 5200an equipment
Qe1系統在系統初始化時，通過軟體完成對硬體晶元pm4354的初始化工作后，便可利用該晶元完成4路e1的同步（位同步、幀同步和復幀同步） ；在pm4354完成時鐘提取的任務后， qe1通過不斷地訪問pm4354的狀態寄存器，獲得每路e1的狀態信息，在時鐘源的選擇原則下，選擇指定e1線路的恢復時鐘作為整個htc - 5200an節點設備的外部參考時鐘，從而解決了htc 5200an的中繼板卡由e1變為qe時所帶來的網同步時鐘源。Four benchmark test sequences was used for the simulation, and the average number of cycles required to process a frame of the proposed architecture and average number of reference memory access required per frame has been computed
本文用四個標準測試序列對所設計結構進行了模擬實驗，統計了該結構平均完成一次塊匹配的時鐘周期和平均處理一幀需對參考塊數據存儲器的訪問次數。
