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

摘要

A method for dependency broadcasting through a source organized source view data structure is disclosed. The method comprises receiving an incoming instruction sequence using a global front end and grouping the instructions to form instruction blocks. Further, the method comprises 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 instruction blocks wherein an incoming instruction block writes its respective block number into fields of the register template corresponding to destination registers referred to by the incoming instruction block. The method also comprises populating a source organized source view data structure, wherein the source view data structure stores the instruction sources corresponding to the instruction blocks as read from the register template by incoming instruction blocks.

1. A method for dependency broadcasting through a source organized source view data structure, the method comprising:
receiving an incoming instruction sequence using a global front end; grouping the instructions to form instruction blocks; 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 instruction blocks wherein an incoming instruction block writes its respective block number into fields of the register template corresponding to destination registers referred to by the incoming instruction block; populating a source organized source view data structure, wherein the source view data structure stores the instruction sources corresponding to the instruction blocks as read from the register template by incoming instruction blocks; upon dispatch of one block of the instruction blocks, broadcasting a number belonging to the one block to a row of the source view data structure that relates to the one block and marking sources of the row accordingly; and updating dependency information of remaining instruction blocks in accordance with the broadcast.
