A method for selecting an entry of a queue in an out-of-order processor includes: acquiring a tag value of each entry in the queue; generating a mask bit vector of the queue based on the tag value of each entry; generating an executable bit vector of the queue based on whether a corresponding entry in the queue satisfies an executable condition; generating a selection bit vector of the queue based on the mask bit vector and the executable bit vector; and determining an entry corresponding to a target bit in the selection bit vector as an executable entry, in which the target bit is a first bit in the selection bit vector, and a value of the first bit is equal to a first preset value.

A method for solving a Cache address alias and an apparatus for solving a Cache address alias are provided. The method includes determining a corresponding first virtual address based on a received access instruction; querying an address maintenance list to determine a target item corresponding to the first virtual address when an access based on the first virtual address is not hit, information recorded in the target item including a target Tag, a target address alias bit, and a target Cache; determining a second virtual address based on the first virtual address and the target item, and setting information in the second virtual address to be invalid, in which the second virtual address and the first virtual address are mapped to the same physical address; and acquiring information corresponding to the access instruction and writing it back to the first virtual address.
