摘要

文中揭露一种经由周边设备控制资料流之周边设备控制装置，周边设备控制装置包括：周边设备控制处理器，其可控制一或多周边设备之作业；以及汇流排，经适应以连接周边设备控制处理器、主处理器、一或多周边设备，主处理器系配置于周边设备控制装置外以控制一或多周边设备之作业，其中汇流排储存由主处理器及周边设备控制处理器参考之位址以存取一或多周边设备，且汇流排禁止周边设备控制处理器存取周边设备，同时主处理器启动。; and a bus adapted to connect the peripheral equipment control processor, a main processor, and the one or more peripheral equipment, the main processor being provided outside the peripheral equipment control device to control the operation of the one or more peripheral equipment, in which the bus stores addresses that are referenced by the main processor and the peripheral equipment control processor to access the one or more peripheral equipment, and the bus prohibits access to the peripheral equipment by the peripheral equipment control processor while the main processor is active.
