A method of decoding an encoded bitstream. The method includes performing a two-table lookup. A first table is addressed in response to a first plurality of bits from the bitstream. An address into a second table is generated using a value in an entry in said first table accessed in the addressing step. A value (representing the decoded value corresponding to the codeword in the bitstream) in an entry in said second table at the address from the generating step is output.

A system for using actuators to control an image sensor and/or lens based on sensor data received from position sensors and position information for the image sensor and/or lens received from a host processor includes a primary camera controller device, at least one secondary camera controller device, and at least one communication link connecting the primary camera controller device and the secondary camera controller device. The primary camera controller device processes the received sensor data and the received position information to generate control data, sends a secondary portion of the control data to the secondary camera controller device via the communication link, and drives a primary portion of the control data to the actuators. The secondary camera controller device drives the received secondary portion of the control data to the actuators concurrently with the primary camera controller device driving the primary portion of the control data to the actuators.

A system for using actuators to control an image sensor and/or lens based on sensor data received from position sensors and based on position information for the image sensor and/or lens received from a host processor includes a primary camera controller device, at least one secondary camera controller device, and at least one communication link connecting the primary camera controller device and the at least one secondary camera controller device. The primary and secondary camera controller devices receive respective primary and secondary sensor data from the position sensors, send the respective primary and secondary sensor data to the other camera controller device via the communication link, process the primary and secondary sensor data and the position information to generate respective primary and secondary control data, and drive the respective primary and secondary control data to the actuators concurrently.

A system may include a processing engine and an analog-to-digital conversion interface subsystem communicatively coupled to the processing engine. The processing engine may be configured to process feedback data converted from analog feedback data to digital feedback data, wherein the feedback data includes a plurality of data stream sequences converted from the analog feedback data to the digital feedback data at a sample rate and based on processing of the feedback data, generate digital control signals for controlling a system under control. The analog-to-digital conversion interface subsystem may be configured to flexibly control the processing of the processing engine and the generation of digital control signals by the processing engine to minimize latency in the generation of the digital control signals due to processing of the processing engine.

A system for reading a plurality of subset views of an evolving data store may include for each subset view, a plurality of memory buffers comprising at least three buffers. The system may also include control circuitry for controlling the plurality of memory buffers of the plurality of subset views, the control circuitry configured to maintain, for each subset view, a variable defining a most-recently updated buffer of the plurality of buffers such that a read request for such subset view will respond with data of the most-recently updated buffer of such subset view; and responsive to an update of data of the evolving data store (i): determine, for each subset view, a selected data buffer of the plurality of buffers other than the most-recently updated buffer for such subset view to write updated subset view information; (ii) cause, for each subset view, the updated subset view information for such subset view to be written to the selected data buffer for such subset view; and (iii) substantially simultaneously across all of the plurality of subset views, update the variables defining the most-recently updated buffer of the plurality of subset views such that a subsequent read request for a subset view will respond with the updated subset view information for such subset view.

A system for atomically transferring vectors of data from a transmitter of the vectors of data to a receiver of the vectors of data may include a plurality of memory buffers configured to store the vectors of the data, each buffer configured to store one vector of the vectors of data at a time, the plurality of memory buffers comprising at least three memory buffers and a controller for controlling the plurality of memory buffers. The controller may be configured to, responsive to a condition for transferring information represented by the vectors of data to the receiver, determine which of the plurality of buffers from which the receiver may receive most-recently updated information completely written to the plurality of buffers by the transmitter. The controller may further be configured to, responsive to a condition for updating information represented by the vectors of data, determine which of the plurality of buffers for the transmitter to write updated information without blocking atomic receipt by the receiver of information from a most-recently updated buffer.
