METHOD FOR POPULATING AND INSTRUCTION VIEW DATA STRUCTURE BY USING REGISTER TEMPLATE SNAPSHOTS

摘要

A method for populating an instruction view data structure by using register template snapshots. 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 and instruction view data structure, wherein the instruction view data structure stores instructions corresponding to the instruction blocks as recorded by the plurality of register templates; and using the instruction view data structure to feed a plurality of stacked execution units of execution stage in accordance with the readiness of instruction sources of the instruction blocks.
