Abstract: A method of reducing kernel computations; the method comprising ordering a plurality of kernel channels. A first of the ordered kernel channels is then convolved with input data to produce a convolution output, and it is determined whether to convolve one or more subsequent kernel channels of the ordered kernel channels. Determining whether to convolve subsequent kernel channels comprises considering a potential contribution of at least one of the one or more subsequent kernel channels in combination with the convolution output.

Abstract: A system includes a fixed-point accumulator for storing numbers in an anchored fixed-point number format, a data interface arranged to receive a plurality of weight values and a plurality of data values represented in a floating-point number format, and logic circuitry. The logic circuitry is configured to: determine an anchor value indicative of a value of a lowest significant bit of the anchored fixed-point number format; convert at least a portion of the plurality of data values to the anchored fixed-point number format; perform MAC operations between the converted at least portion and respective weight values, using fixed-point arithmetic, to generate an accumulation value in the anchored fixed-point number format; and determine an output element of a later of a neural network in dependence on the accumulation value.

Abstract: When processing regions of interest in frames in a data processing system that can execute a plurality of neural networks that are each configured to more optimally process a region of interest of a respective size, a region of interest is first identified within a frame, the size of the region of interest is determined, and one of the plurality of available neural networks is selected to use to process the region of interest based on the determined size. The region of interest is scaled to produce a scaled version of the region of interest, where the scaling is determined based on the selected neural network. The scaled version of the region of interest is then processed using the selected neural network.

Abstract: An AR system includes a user interface, one or more sensors arranged to generate sensor data representing part of an environment in which a user of the AR system is located, and a memory. The memory is arranged to store object association data associating the user with one or more objects in the environment, and object location data indicating a respective location of each of the one or more objects. The AR system is arranged to determine a position of the user; determine an updated location of one of the one or more objects in dependence on the generated sensor data and the determined position of the user, update the stored object location data to indicate the determined updated location of said one of the one or more objects, and output information depending on the updated location of said one of the one or more objects via the user interface.

Abstract: An extended-reality system is described which determines extended-reality data to be obtained from the remote network-connected storage based on a location of the extended-reality system. The extended-reality system determines a communication method by which to obtain the extended-reality data, wherein the extended-reality data may be obtained by one or more requests to the remote network-connected storage or by one or more requests to a local device outside of the extended-reality system. A request is sent to at least one of the local device via a peer-to-peer network and the remote network-connected storage in dependence upon the determination by the extended-reality system.

Abstract: There is provided a display apparatus to focus light for a user. The apparatus comprises a tuneable lens having controllable optical properties, an eye-tracker device to determine a position at which the user is looking, and circuitry to control the optical properties of the tuneable lens to bring an object at the depth of the position into focus for the user. A method of focusing light is also provided. The method comprises determining a position at which the user is looking and controlling optical properties of a tuneable lens to bring an object at the depth of the position into focus for the user.

Abstract: Herein described is a method of operating an accumulation process in a data processing apparatus. The accumulation process comprises a plurality of accumulations which output a respective plurality of accumulated values, each based on a stored value and a computed value generated by a data processing operation. The method comprises storing a first accumulated value, the first accumulated value being one of said plurality of accumulated values, into a first storage device comprising a plurality of single-bit storage elements; determining that a predetermined trigger has been satisfied with respect to the accumulation process; and in response to the determining, storing at least a portion of a second accumulated value, the second accumulated value being one of said plurality of accumulated values, into a second storage device.

Abstract: A human-machine interface system comprises a sensor configured to generate data associated with a human movement, such as measured electrical signals or data from an accelerometer. A measurement unit of the human-machine interface measures user movement over time to generate a sequence of measured user movement data. A processor processes the data associated with a human movement from the sensor using a trained neural network to determine one or more predicted user actions. A comparison unit compares the one or more predicted user actions with one or more user actions obtained from the sequence of measured user movement data. A control unit uses the predicted user actions to control a process in an information processing apparatus in dependence upon the comparison performed by the comparison unit.
