Embodiment Construction
[0084] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0085] The vector VLIW architecture diagram coloring register group allocation method of the present invention is to abstract multiple groups in various registers in advance according to the requirements of the hardware; when register allocation is performed, the appropriate group is allocated according to the requirements of the instruction template where the candidate is located registers in . The method of the present invention takes the graph coloring method as the basic idea, improves and optimizes the following links on the basis of the typical graph coloring global register allocation method: analysis of register allocation candidates' attributes related to register requirements, conflict relationship analysis, register allocation Merge, Conflict Graph Pruning, Physical Register Assignment.
[0086] The method of the present i...
