We disclose a function unit based finite state automata data structure for use in computer program compilers. According to an aspect of an embodiment, the data structure comprises a function unit vector, having no more used bits than there are issue ports for any particular microprocessor, and a plurality of valid template assignments for each function unit vector. In a preferred embodiment, the template assignments are constructed so as to account for dispersal rules associated with the particular microprocessor. Further, the template assignments can be sorted according to priority data.

Function unit based finite state automata data structure, transitions and methods for making the same

A compiler comprising an integrated instruction scheduler and resource management system is provided. According to an aspect of an embodiment, the resource management system includes a function unit based finite state automata system. Instructions to be compiled are modeled through the function unit based finite state automata system based on their function unit usage, before they are emitted as compiled computer code. We also disclose a function unit based finite state automata data structure and computer implemented methods for making the same.
