  • REDUCING STALLING IN A SIMULTANEOUS MULTITHREADING PROCESSOR BY INSERTING THREAD SWITCHES FOR INSTRUCTIONS LIKELY TO STALL
    Publication number: 20180336030
    Abstract: A system and method suppresses occurrence of stalling caused by data dependency other than register dependency in an out-of-order processor. A stall reducing method includes a handler for detecting a stall occurring during execution of execution code using a performance monitoring unit, and for identifying, based on dependencies, a second instruction on which a first instruction is data dependent, the stall based on this dependency. A profiler registers the second instruction as profile information. An optimization module inserts a thread yield instruction in an appropriate position inside execution code or an original code file based on the profile information, and outputs optimized execution code.

  • ACCELERATING GENOMIC DATA PARSING ON FIELD PROGRAMMABLE GATE ARRAYS
    Publication number: 20180068000
    Abstract: Methods and systems for accelerated input data conversion include partially parsing an input data set to convert the data set from a first format to a second format in an intermediate output having at least one unparsed portion to quickly perform a majority of the conversion. The partial parsing operates on portions of the input data set having a size less than a threshold size and leaves portions of the input data having a size greater than the threshold size unparsed. The intermediate output is parsed to convert at least one unparsed portion from the first format to the second format in a final output to complete the conversion such that a combined parsing time of the partial parse of the input data set and the parse of the intermediate output is accelerated relative to a single-stage parsing.
