recovery block造句

• To tolerate faults , the techniques rely on redundant implementations , which are n - modular redundancy for building fault - tolerant hardware and n - version programming or recovery blocks method for building fault - tolerant software
  容错的技术在于采用冗余工具，也就是采用n模块冗余构造容错硬件，采用n版本编程或恢复块方法构造容错软件。
• The clock recovery block of usb2 . 0 transceiver macrocell consists of phase locked circuit , such as pll and dll ( delay locked loop ) . this block use external crystal 12mhz sin signal to produce 60mhz , 120mhz , 480mhz clock signal , and can recover colock signal form date wave . it can support 480mbps ( hs ) and 12mbps ( fs ) word speeds as defined in usb2 . 0 specification .
  目的是用锁相环电路? pll和dll (延迟锁相环)实现usb2 . 0收发器宏单元utm的时钟恢复模块。其中pll环路构成的时钟发生器将外部晶振的12mhz正弦信号生成60mhz 、 120mhz 、 480mhz等本地时钟信号。 dll环路依据本地时钟信号对外部数据信号进行时钟恢复。
