27、理器工作模式。(C)A、5B、6C、7D、819.(C)是專門用于信號(hào)處理方面的處理器，其在系統(tǒng)結(jié)構(gòu)和指令算法方面進(jìn)行了特殊設(shè)計(jì)，使其適合于執(zhí)行DSP算法，編譯效率較高，指令執(zhí)行速度也較高。在數(shù)字濾波、FFT、譜分析等各種儀器上DSP獲得了大規(guī)模的應(yīng)用。A.微處理器(MicroprocessUnitMPU)B.微控制器(MicrocontrollerUnitMCU)C.嵌入式DSP(EmbeddedDigitalSignalProces

28、sEDSP)D.片上系統(tǒng)(SystemOnChip，SoC)E.多核微處理器20.ARM（AdvancedRISCMachines）既可以認(rèn)為是一個(gè)公司的名字，也可以認(rèn)為是對(duì)一種微處理器體系結(jié)構(gòu)的通稱。1990年11月ARM公司成立于英國劍橋，設(shè)計(jì)了大量高性能、廉價(jià)、耗能低的(A)處理器。A.RISCB.CISC21.在計(jì)算機(jī)體系結(jié)構(gòu)中，(C)表示每條計(jì)算機(jī)指令執(zhí)行所需的時(shí)鐘周期。A.時(shí)鐘周期(節(jié)拍)B.機(jī)器周期C.CPID.總線周期2
