Abstract: A method, an apparatus, and a computer program product for optimally tuning a memory card in a host device are provided. The apparatus determines at least one tuning parameter associated with the memory card, initiates a reading operation with the memory card, and sends a tuning command to the memory card based on the at least one tuning parameter. The at least one tuning parameter includes a temperature of the memory card, a time elapsed since a last tuning sequence was performed, a number of data blocks sent from the memory card to the host device, and/or a number of transactions between the memory card and the host device. The apparatus also reads data from the memory card, detects a cyclic redundancy check (CRC) error associated with the read data, and sends the tuning command to the memory card upon detecting the CRC error.

Abstract: Systems and methods to transfer master duties to a slave on a communication bus are disclosed. A master of a communication bus determines that one or more slaves are capable of serving as a sub-master, including providing a clock signal and owning control information bits. Once that determination is made, the master may determine that processing within the master is not required for a particular activity on the bus. The master then alerts one such capable slave to prepare to assume sub-master duties. Once the slave confirms that the slave is ready to assume the sub-master duties, the master may transmit a handover frame on the bus, and the slave begins acting as a sub-master. The master may then enter a low-power state, which may promote power savings, reduce heat generation, and provide other advantages.

Abstract: Data bus activation in an electronic device is provided. In one aspect, a host circuit determines a cumulative potential representing a cumulative fractional bus activation vote on a data line(s) in the data bus. The host circuit activates the data bus when the cumulative potential is greater than a configurable bus activation threshold. In another aspect, a device circuit(s) determines a selected signal strength threshold that is less than determined signal strength of an incoming signal. Accordingly, the device circuit(s) asserts a fractional potential corresponding to the selected signal strength threshold on the data line(s) as a fractional bus activation vote in the cumulative fractional bus activation vote. By activating the data bus based on the cumulative fractional bus activation vote, the host circuit can support timely data bus activation while preventing the data bus from being falsely activated, thus improving robustness of data bus activation in the electronic device.

Abstract: Techniques and systems are provided for processing one or more frames or images. For instance, a process for determining exposure for one or more frames includes obtaining a motion map for one or more frames. The process includes determining, based on the motion map, motion associated with the one or more frames of a scene. The motion corresponds to movement of one or more objects in the scene relative to a camera used to capture the one or more frames. The process includes determining, based on the determined motion, a number of frames and an exposure for capturing the number of frames. The process further includes sending a request to capture the number of frames using the determined exposure duration.

Abstract: Methods, apparatuses, systems, and computer-readable media for dynamically improving performance of a host memory controller and a hosted memory device are presented. According to one or more aspects, a memory controller may establish a data connection with a memory device. The memory controller may perform a first write operation of a plurality of write operations to the memory device using a first block size. Subsequently, the memory controller may perform a second write operation of the plurality of write operations to the memory device using a second block size different from the first block size. The memory controller then may determine an optimal value for a block size parameter based at least in part on the plurality of write operations. Thereafter, the memory controller may use the optimal value for the block size parameter in performing one or more regular tasks involving the memory device.
