complete cpu control of intelligence protects the electric circuit 智能完整cpu控制保護電路
the cpu control unit transforms a linear address into a physical address automatically cpu會自動把一個虛地址映射成一個物理地址。
it is based on single cpu control and multilevel software, which simplified the hardware and redued the respond time of the system 該方案采用單級cpu控制,簡化了系統(tǒng)硬件,并縮短了系統(tǒng)響應(yīng)時間。
the mcf5249 works as the main processor on the cpu control board . the main task of the control logic finished on fpga is assisting mcf5249 with controlling the 控制邏輯的主要任務(wù)是協(xié)助cpu主控板中的主控制器mcf5249完成對分接復(fù)用板上的pm4329,pm5332,pm5366,pm5320等芯片的控制操作。
one is the multiplexer-demultiplexer board, the other is the cpu control board . the first board is used to finish the function of signal demultiplexing while the latter board is used to controle the configuration of the first 其中,sdh分接復(fù)用板用來實現(xiàn)系統(tǒng)所要求的各種信號分接等功能;cpu主控板用來對sdh分接復(fù)用板進行配置和控制。
