專利摘要(英)
A method for copy propagations of a processor including two clusters, each cluster comprising a first function unit and a second function unit, a first local register file and a second local register file being respectively accessible by the first and second function unit only, and a global register file having a ping-pong structure to access the first and second local register files, the method comprising the steps of: (a) listing possible copy propagation paths between two nodes of a data flow graph; (b) calculating a profit of machine cycles for each of the copy propagation paths according to constraints of the processor; and (c) performing a copy propagation through the copy propagation path if the profit thereof is greater than a threshold value.
