Suresh Doraiswamy 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).

  • Dynamically adjusting power of non-core processor circuitry including buffer circuitry
    Patent number: 9501129
    Abstract: In one embodiment, the present invention includes a multicore processor having a variable frequency domain including a plurality of cores and at least a portion of non-core circuitry of the processor. This non-core portion can include a cache memory, a cache controller, and an interconnect structure. In addition to this variable frequency domain, the processor can further have a fixed frequency domain including a power control unit (PCU). This unit may be configured to cause a frequency change to the variable frequency domain without draining the non-core portion of pending transactions. Other embodiments are described and claimed.
    Type: Grant
