Abstract: A method and an apparatus for determining a physical address are disclosed. According to the present disclosure, a page size is obtained according to the higher-order N bits of a linear address, where N is greater than 0 and less than a quantity of bits of the linear address; an index number of a translation lookaside buffer TLB is obtained according to the page size; a mask is obtained according to the page size and a supported minimum page size; a label of the TLB is obtained according to the mask; the higher-order MAC1 bits of a physical address corresponding to the linear address are obtained by searching the TLB according to the index number and the label; and the physical address is obtained according to the mask, the supported minimum page, and the higher-order MAC1 bits of the physical address.

Abstract: A method and an apparatus for accessing physical resources, is used to restrict access to physical resources of other light system kernel Light OSs by a first Light OS in a multi-kernel operating system and ensure security of accessing physical resources among the Light OSs. A method, executed by secure firmware, includes: receiving a physical address corresponding to a physical resource to be accessed by the first Light OS; determining whether the physical address corresponding to the physical resource is out of bounds; and if the physical address corresponding to the physical resource is within bounds, sending an access continuity signal to the first Light OS; or if the physical address corresponding to the physical resource is out of bounds, sending an access error signal to the first Light OS.

Abstract: A memory system and a memory module access method are provided. The memory system includes a memory controller and a plurality of memory modules. The memory modules are interconnected for forwarding access requests received from the memory controller. When a first memory module receives an access request, if it is not the destination of the access request, it forwards the access request to a second memory module. The second memory module processes the access request if it is the destination of the access request.
