METHOD FOR DEPENDENCY BROADCASTING THROUGH A BLOCK ORGANIZED SOURCE VIEW DATA STRUCTURE

摘要

A method for dependency broadcasting through a block organized source view data structure. The method includes receiving an incoming instruction sequence using a global front end; grouping the instructions to form instruction blocks; using a plurality of register templates to track instruction destinations and instruction sources by populating the register template with block numbers corresponding to the instruction blocks, wherein the block numbers corresponding to the instruction blocks indicate interdependencies among the blocks of instructions; populating a block organized source view data structure, wherein the source view data structure stores sources corresponding to the instruction blocks as recorded by the plurality of register templates; upon dispatch of one block of the instruction blocks, broadcasting a number belonging to the one block to a column of the source view data structure that relates that block and marking the column accordingly; and updating the dependency information of remaining instruction blocks in accordance with the broadcast.
