Patent number: 10685630Abstract: According to various aspects, just-in-time system bandwidth changes may be implemented in hardware to optimize power consumption and performance in an electronic device. More particularly, in a periodic system associated with an electronic device, a bandwidth for a next frame may be configured during a current frame via software operating on the electronic device. Hardware associated with the periodic system may issue a bandwidth change request for the next frame when a current time reaches a bandwidth increase threshold in response to actual processing time associated with the current frame finishing prior to the bandwidth increase threshold, which may be defined relative to a timer deadline that defines when the next frame starts to process.Type: GrantFiled: June 8, 2018Date of Patent: June 16, 2020Assignee: QUALCOMM IncorporatedInventors: Carlos Javier Moreira, Paul Chow, Dhaval Kanubhai Patel

Patent number: 10445902Abstract: Techniques are described in which a device is configured to retrieve a metadata buffer for rendering a sub-frame of a set of sub-frames for a frame. A data block of a data buffer is configured to store image data for rendering the sub-frame. In response to determining, based on the metadata buffer for rendering the sub-frame, that the sub-frame includes a color pattern, fixed color value, or combination thereof, the device refrains from retrieving the image data from the data block of the data buffer and determines the image data for rendering the sub-frame based on the metadata buffer.Type: GrantFiled: December 13, 2016Date of Patent: October 15, 2019Assignee: QUALCOMM IncorporatedInventors: Andrew Evan Gruber, Serag GadelRab, Zhenbiao Ma, Meghal Varia, Tao Wang, Tom Longo, Mark Sternberg, Paul Chow

Patent number: 9864647Abstract: A method and system for adjusting bandwidth within a portable computing device based on danger signals monitored from one on more elements of the portable computing device are disclosed. A danger level of an unacceptable deadline miss (“UDM”) element of the portable computing device may be determined with a danger level sensor within the UDM element. Next, a quality of service (“QoS”) controller may adjust a magnitude for one or more danger levels received based on the UDM element type that generated the danger level and based on a potential fault condition type associated with the particular danger level. The danger levels received from one UDM element may be mapped to at least one of another UDM element and a non-UDM element. A quality of service policy for each UDM element and non-UDM element may be mapped in accordance with the danger levels.Type: GrantFiled: January 2, 2015Date of Patent: January 9, 2018Assignee: QUALCOM IncorporatedInventors: Serag Gadelrab, Cristian Duroiu, Vinod Chamarty, Pooja Sinha, John Daniel Chaparro, Anil Vootukuru, Vinodh Ramesh Cuppu, Joseph Schweiray Lee, Vinay Mitter, Paul Chow, Ruolong Liu, Johnny Jone Wai Kuan

Publication number: 20160127259Abstract: A method and system for managing safe downtime of shared resources within a portable computing device are described. The method may include determining a tolerance for a downtime period for an unacceptable deadline miss element of the portable computing device. Next, the determined tolerance for the downtime period may be transmitted to quality-of-service (“QoS”) controller. The QoS controller may determine if the tolerance for the downtime period needs to be adjusted. The QoS controller may receive a downtime request from one or more shared resources of the portable computing device. The QoS controller may determine if the downtime request needs to be adjusted. Next, the QoS controller may select a downtime request for execution and then identify which one or more unacceptable deadline miss elements of the portable computing device that are impacted by the selected downtime request.Type: ApplicationFiled: January 2, 2015Publication date: May 5, 2016Inventors: CRISTIAN DUROIU, VINOD CHAMARTY, SERAG GADELRAB, MICHAEL DROP, POOJA SINHA, RUOLONG LIU, JOHN DANIEL CHAPARRO, VINODH RAMESH CUPPU, JOSEPH SCHWEIRAY LEE, JOHNNY JONE WAI KUAN, PAUL CHOW, ANIL VOOTUKURU, VINAY MITTER
