Partitioning method and device of digit group multi-reference access

Provided is a partitioning method and a device of digit group multi-reference access. The partitioning method of the digit group multi-reference access comprises: analyzing digit group access patterns inside each circulation in a program, and analyzing association of digit groups inside each circulation according to the digit group access patterns, wherein the association comprises association type and association distance; according to the association type and the association distance of digit group access, combining memory system architectural features and calculating digit group partitioning parameters and buffer size parameters; and outputting the digit group partitioning parameters and buffer size parameters of the digit group access. The partitioning method of the digit group multi-reference access analyzes correlation among multi-reference access in application programs, considers structural constraint of system memory architecture and guarantees to obtain effective digit group partitioning parameters and buffer size parameters.
