  • Patent number: 11188315
    Abstract: The disclosed systems, apparatuses and methods are directed to optimizing by a compiler register resource allocation for functions of a module, using a Register File comprising a limited number of registers. After performing interprocedural analysis in the module, the compiler computes the number of registers used by each function, and compiles the function to final machine code, except at callsites where a call is detected to be made to another function. At each callsite and for each called function, the compiler expands call instructions to final machine code after computing and setting a relative index to be used by a called function for running in an available part of the Register File. The relative index optimizes register resource allocation by minimizing the number of spilled registers before a function is called.

  • Publication number: 20210318875
    Abstract: A method for grouping computer instructions includes receiving a set of computer instructions, grouping the set of computer instructions by register dependencies, identifying a plurality of single-definition-use flow (SDF) bundles based on a burstization criteria and a chaining criteria; and based on the SDF bundles, transforming the set of computer instructions. The transformation may include splitting one of the set of computer instructions and setting a burst parameter for the one of the set of computer instruction. The transformation may include grouping a plurality of the set of computer instructions and replacing a pair of register file accesses with a pair of temporary register accesses.

  • Publication number: 20210004213
    Abstract: A method for improving the performance of applications executed within asynchronous processor architectures. In an embodiment, a method for improving execution time of compiled synchronized source code on an asynchronous processor architecture includes receiving, by a processing system, synchronized source code comprising synchronization instructions to synchronize execution of the synchronized source code on different pipelines of the asynchronous processor architecture. The method also includes analyzing, by the processing system, the synchronized source code to determine whether the synchronized source code includes a broken code condition.
