Title: Tracing branch instructions
Inventor: JOHN MICHAEL HORLEY
IPC: G06F11/36
Filed: 2018-03-13
Abstract: A processor receives a sequence of instructions comprising branch instructions. Trace circuitry generates a trace stream indicative of data processing operations. The trace circuitry is responsive to one or more not-taken branch instructions followed by a taken branch instruction 102 to check a status condition 106. If the condition is met, a not-taken trace item corresponding to the one or more not-taken branch instructions is added to the trace stream 112, 114, and if the condition is not met include a source address associated with the taken branch instruction in the trace stream 108. A hybrid approach between tracing not-taken branch instructions and tracing a source address associated with the taken branch instruction is thus provided. The apparatus status may be a counter of not-taken branch instructions, or an indication that instructions have been removed from the sequence as part of an optimisation procedure.

Title: Generating or obtaining an updated neural network
Inventor: Francesco Cricri
IPC: G06N3/02
Filed: 2018-03-27
Abstract: A method or apparatus of obtaining an updated neural network from a base neural network by obtaining an order of unit (e.g. layer, filter, node) updates and providing the update information to another neural network. The update is based on a metric which may improve the accuracy of a NN task (e.g. NN learning). Identical base neural networks may reside on a server and a remote device (e.g. a mobile phone or an IoT device). The method may be implemented using algorithm 40 which updates each of an i-unit of the n-unit base NN by incrementing the value i and updating the weights of each unit. At each iteration, the units of the NN may be frozen and only the i-th unit is fine tuned. After this step the update information may be sent to the remote device (step 48). The method may provide an improvement in communications and/or data privacy and may be implemented using a cloud-hosted application. A second invention concerns an n-unit NN from an n-unit base NN by updating at least one of a plurality of the n-units.
