Order-preserving method and system for multiple sets of load store queues of processor and related device

An order-preserving method for multiple sets of load store queues of a processor, comprising:

• presetting a total depth of the queues;
• wherein the queues comprise multiple sets of sub-queues;
• determining a dimension of an age matrix according to the total depth of the queues;
• initializing the age matrix to obtain initial age information of the age matrix;
• wherein the initial age information comprises entries of the sub-queues;
• updating related positions of corresponding rows and columns in the age matrix according to a time order and recording current age information, in response to both a preset instruction being received and entering the queues;
• and
• initiating a request through the multiple sets of sub-queues, and searching for local and global age information for order-preserving operation,
• wherein initializing the age matrix to obtain the initial age information of the age matrix comprises:
• initializing the current age information in the age matrix in response to the age matrix being initialized and/or clearing the current age information in the age matrix in response to the age matrix being flushed by a processor pipeline;
• acquiring a size of the age matrix according to the total depth of the queues;
• dividing the age matrix according to a number of the multiple sets of sub-queues;
• initializing the age matrix;
• and
• obtaining a queue of the age matrix.
