Abstract: An apparatus and method are provided for handling transactions in a system employing transactional memory. The apparatus has processing circuitry for performing data processing in response to instructions, and transactional memory support circuitry for supporting execution of a transaction within a thread of data processing by the processing circuitry. The transaction comprises a sequence of instructions executed speculatively and for which the processing circuitry prevents commitment of results of those instructions until the transaction has reached a transaction end point. The transactional memory support circuitry comprises abort event detection circuitry that causes execution of the transaction to be aborted when an abort event is detected before the transaction has reached the transaction end point, and which causes abort status information to be stored for later reference when determining whether to retry execution of the transaction.

Abstract: An apparatus comprises processing circuitry to execute instructions, and decode circuitry to decode the instructions for execution by the processing circuitry. The decode circuitry is responsive to an authentication code generation instruction specifying a first source value to control the processing circuitry to generate an authentication code dependent on the first source value, and store the authentication code to a memory location associated with a store address formed using a value obtained from a register. By providing a single instruction, this reduces register pressure enabling improved performance by avoiding unnecessary load/store operations, and makes compilation of code using the authentication code generation instruction simpler.

Abstract: When a graphics processor is processing data for an application on a host processor, the graphics processor generates in advance of their being required for display by the application a plurality of frame sequences corresponding to a plurality of different possible “future states” for the application. The graphics processing system, when producing a frame in a sequence of frames corresponding to a given future state for the application, determines one or more region(s) of the frame that are to be produced at a first, higher quality, and producing the determined region(s) of the frame at a first, higher quality, whereas other regions of the frame are produced at a second, lower quality.

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.

By sharing resources for supporting additional threads and supporting transactions, circuit area and power consumption can be reduced.
