Patents by Inventor Biplob Mishra

Biplob Mishra has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Partial data type promotion to exploit efficient vectorization in microprocessors
    Patent number: 11740880
    Abstract: Aspects of the invention include a compiler detecting an expression in a loop that includes elements of mixed data types. The compiler then promotes elements of a sub-expression of the expression to a same intermediate data type. The compiler then calculates the sub-expression using the elements of the same intermediate data type.
    Type: Grant
    Filed: September 8, 2021
    Date of Patent: August 29, 2023
    Assignee: International Business Machines Corporation
    Inventors: Biplob Mishra, Satish Kumar Sadasivam, Puneeth A. H. Bhat

  • Reconstructing a high level compilable program from an instruction trace
    Patent number: 10691419
    Abstract: Mechanisms are provided for generating a new compilable program from an instruction trace. The mechanisms receive a trace file for an original program whose execution on computing hardware has been traced and perform analysis of the trace file to identify a hot function, symbol information corresponding to the hot function, and initialization parameters for the hot function. The mechanisms generate a trace control flow graph based on the identified hot function and the symbol information corresponding to the hot function. The mechanisms identify, based on the trace control flow graph, pathways in the original program to the hot function, represented in the trace file. The mechanisms generate a reconstructed program based on the trace control flow graph, the pathways to the hot function, and the initialization parameters, and output the reconstructed program.
