Patent number: 11966341Abstract: Methods that may be performed by a host controller of a computing device for synchronizing logical-to-physical (L2P) tables before entering a hibernate mode are disclosed. Embodiment methods may include determining whether a first L2P table stored in a dynamic random-access memory (DRAM) communicatively connected to the host controller is out of synchronization with a second L2P table stored in a static random-access memory (SRAM) of a universal flash storage (UFS) device communicatively connected to the host controller via a link. If the first and second L2P tables are out of synch, the host controller may retrieve at least one modified L2P map entry from the second L2P table when the UFS device is configured to enter a hibernate mode from the UFS device, and update the first L2P tabled with the at least one modified L2P map entry before the link and the UFS device enter the hibernate mode.Type: GrantFiled: November 10, 2022Date of Patent: April 23, 2024Assignee: QUALCOMM IncorporatedInventors: Madhu Yashwanth Boenapalli, Surendra Paravada, Sai Praneeth Sreeram

Patent number: 11800342Abstract: A method may involve receiving fingerprint sensor data from a fingerprint sensor system, detecting, according to the fingerprint sensor data, a presence of a digit on an outer surface of the apparatus in a fingerprint sensor system area; determining, according to the fingerprint sensor data, a digit force or a digit pressure of the digit on the outer surface of the apparatus; and making, according to the fingerprint sensor data, a time threshold determination. The time threshold determination may involve determining whether a length of time during which the digit force exceeds a threshold digit force or during which the digit pressure exceeds a threshold digit pressure is greater than or equal to a threshold length of time. The method may involve determining, based at least in part on the time threshold determination, whether to enable one or more emergency response functions of the apparatus.Type: GrantFiled: September 20, 2021Date of Patent: October 24, 2023Assignee: QUALCOMM IncorporatedInventors: Sai Praneeth Sreeram, Surendra Paravada, Madhu Yashwanth Boenapalli, Bipul Tarafdar

Patent number: 11782837Abstract: Systems and methods for fast memory access are disclosed. In one aspect, a processor such as, for example, a control circuit in a system on a chip (SoC) that couples to an external memory such as, for example a Universal File System (UFS) memory (e.g., a NAND flash memory) with a partial logical to physical (L2P) mapping table stored in the external memory as well as a local L2P mapping table stored in a local memory (e.g., dynamic random-access memory (DRAM)). The control circuit may evaluate what percentage of entries in the local L2P mapping table are active compared to inactive. If the number of inactive exceeds the number of active, the control circuit may send a read command without accessing the local L2P mapping table.Type: GrantFiled: November 4, 2021Date of Patent: October 10, 2023Assignee: QUALCOMM IncorporatedInventors: Madhu Yashwanth Boenapalli, Sai Praneeth Sreeram, Surendra Paravada

Publication number: 20210263720Abstract: Systems and methods for flash memory conflict avoidance cause a firmware over the air (FOTA) update to be given priority over a scrubbing operation unless the memory element meets or exceeds a predefined health degradation parameter. When the memory element meets or exceeds the predefined health degradation parameter, the scrubbing operation is given priority over the FOTA update. By enforcing these priorities, scrubbing and FOTA updates do not occur at the same time and conflicts are thereby avoided. Since conflicts are avoided, the chance of memory corruption is decreased and the chance of “bricking” the computing device is likewise decreased.Type: ApplicationFiled: February 24, 2020Publication date: August 26, 2021Inventors: Madhu Yashwanth Boenapalli, Sai Praneeth Sreeram, Surendra Paravada, Venu Madhav Mokkapati

Patent number: 10769079Abstract: In a conventional system with a UFS storage device connected to a UFS host over one or more lanes, the lanes can support different transmission speeds, referred to as gears. The UFS host shifts lanes and gears based on the type of request it receives. When the requests arrive in random order of gear requirements, the frequent shifting of the lanes and gears causes significant power consumption. To address this issue, it is proposed to implement a queue-based shifting in which arriving requests may be queued based on their gear requirements. When a queue is selected, multiple requests in the selected queue, which are all of same or similar gear requirement, can be served. This can reduce the frequency of gear shifting, and hence reduce power consumption.Type: GrantFiled: March 27, 2018Date of Patent: September 8, 2020Assignee: QUALCOMM IncorporatedInventors: Madhu Yashwanth Boenapalli, Venu Madhav Mokkapati, Surendra Paravada

Patent number: 10630568Abstract: Systems, methods, and apparatus for rewriting or adjusting a TCP timestamp value are described. The methodology includes determining network conditions of a wireless network, and establishing a transmission control protocol (TCP) connection between a first communication device and a second communication device via the wireless network. The timestamp value within a TCP packet to be transmitted, such as as a TCP SYN ACK packet in a 3-way handshake, is adjusted with the use of a timestamp adjusting circuitry or hardware, where the adjustment is based on the determined network conditions. By adjusting the timestamp of a TCP packet prior to transmission and based on network conditions, unnecessary retransmissions are reduced. Additionally, the use of timestamp adjusting hardware allows for more efficient timestamp adjustment by offloading processor computations.Type: GrantFiled: September 7, 2018Date of Patent: April 21, 2020Assignee: Qualcomm IncorporatedInventors: Venu Madhav Mokkapati, Gurudutt Narasimha, Uday Kumar Arava, Madhu Yashwanth Boenapalli
