Abstract: A method for accessing data is provide, the method includes: receiving a first address and identification information used to identify an address type; and when the identification information indicates a logical address type, converting the first address into a first physical address, and accessing at least one corresponding flash memory chip in the storage device; or when the identification information indicates a physical address type, directly accessing at least one corresponding flash memory chip in the storage device. When the storage device is accessed, a type of an accessed address is determined according to the identification information. If the address is a logical address, the storage controller maps the logical address to a physical address and accesses the physical address; or if the address is a physical address, the storage controller directly accesses the physical address sent by the host.

Abstract: A method for setting a working mode of a multi-processor system includes: detecting, after a current board is inserted into a slot of the backplane, whether an associated board exists on the backplane; detecting, if the associated board exists, whether the associated board is in an independent working state; powering on the current board according to a slave working mode if the associated board is not in an independent working state, so as to work coordinately with the associated board; detecting, within a predetermined detection time if the associated board does not exist, whether a board is inserted into another slot of the backplane except the slot of the master board; and powering on the current board according to a master working mode if it is detected that the board is inserted, so as to work coordinately with the board in the other slot.
Abstract translation: 一种用于设置多处理器系统的工作模式的方法，包括：在当前板插入到背板的槽中之后，检测背板上是否存在相关的板; 如果相关的板存在，检测相关板是否处于独立工作状态; 如果相关的董事会不处于独立工作状态，则按照从属工作模式开启当前的董事会，以便与相关的董事会协调工作; 在相关板不存在的预定检测时间内检测板是否被插入除了主板的槽之外的背板的另一个槽中; 如果检测到板插入，则根据主工作模式对当前板进行上电，以便与另一个插槽中的板协调工作。
