Navaneetha K Ruthramoorthy 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).

  • Patent number: 9032380
    Abstract: A device receives program code, generated via a technical computing environment (TCE) and including code that requires further processing to execute, and identifies one or more function calls or one or more object method calls in the program code. The device creates a control flow graph, for the program code, based on the one or more function calls or the one or more object method calls. The device transforms the control flow graph into a data flow graph. The data flow graph includes a representation for each of the one or more function calls or the one or more object method calls. The device generates hardware code based on the data flow graph, the hardware code including code that does not require further processing to execute.

  • Publication number: 20130238344
    Abstract: The present invention provides a computationally efficient technique for compression encoding of an audio signal, and further provides a technique to enhance the sound quality of the encoded audio signal. This is accomplished by including more accurate attack detection and a computationally efficient quantization technique. The improved audio coder converts the input audio signal to a digital audio signal. The audio coder then divides the digital audio signal into larger frames having a long-block frame length and partitions each of the frames into multiple short-blocks. The audio coder then computes short-block audio signal characteristics for each of the partitioned short-blocks based on changes in the input audio signal.
