Patents by Inventor Avinash N. Ananthakrishan

Avinash N. Ananthakrishan 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).

  • Performing cross-domain thermal control in a processor
    Patent number: 9063727
    Abstract: In an embodiment, a processor includes a first domain with at least one core to execute instructions and a second domain coupled to the first domain and including at least one non-core circuit. These domains can operate at independent frequencies, and a power control unit coupled to the domains may include a thermal logic to cause a reduction in a frequency of the first domain responsive to occurrence of a thermal event in the second domain. Other embodiments are described and claimed.
    Type: Grant

  • Controlling temperature of multiple domains of a multi-domain processor using a cross domain margin
    Patent number: 8954770
    Abstract: In one embodiment, the present invention includes a method for determining, in a controller of a multi-domain processor, whether a temperature of a second domain of the multi-domain processor is greater than a sum of a throttle threshold and a cross-domain margin, and if so, reducing a frequency of a first domain of the multi-domain processor by a selected amount. In this way, a temperature of the second domain can be allowed to reduce, given a thermal coupling of the domains. Other embodiments are described and claimed.
