Senthil Somasundaram 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: 8264210
    Abstract: A method and apparatus to regulate voltage used to power an ASIC comprising an ASIC having a signal source and a modulator. The modulator establishes a characteristic of a signal created by the signal source to indicate a voltage level to be used to power the ASIC. The signal is communicated to a voltage regulator to apply an optimal voltage to the ASIC.
    Type: Grant

  • Patent number: 8051346
    Abstract: Systems, methods, and other embodiments associated with programmable application specific integrated circuit (ASIC) fault injection are described. One example ASIC includes a serializer de-serializer (SERDES). The example ASIC may also include logics to process data in the ASIC. At least one of the logics either receives data from the SERDES and/or provides data to the SERDES. The example ASIC may also include an embedded fault injection logic (EFIL) to control injection of a fault to a path (e.g., data, control) associated with at least one of the logics. The example ASIC may also include an embedded set of multiplexers (ESOMs) controlled by the EFIL. The ESOMs are controllable by the EFIL to inject a fault signal to the data path.

  • Patent number: 7908533
    Abstract: Method and apparatus for operating for operating an Institute of Electrical and Electronics Engineers (IEEE) Standard 1149.1 compliant Joint Test Action Group (JTAG) Test Access Port (TAP) controller are disclosed. An example apparatus includes write logic that is configured to operationally interface with a TAP controller and a processor. The write logic is further configured to receive, from the processor, data for initializing the apparatus and operating the TAP controller, convert at least a portion of the data from a parallel format to a serial format and communicate the converted data to the TAP controller.
