The interface mapping unit includes physical registers that act as physical register input/output interfaces for the accelerator. The interface mapping unit exposes a plurality of virtual accelerator input/output interfaces to the applications that are then dynamically mapped to the physical register input/output interfaces by the interface mapping unit to allow applications to access, and thereby submit a task to, a given physical register input/output interface.

Abstract: A data processing apparatus has multiple caches and a controller for controlling the caches. The controller and caches communicate over a first network and a second network. The first network is used for unicast communication from the controller to a specific one of the caches. The second network is used for communication of a multicast communication from the controller to two or more of the caches.

Abstract: A method in a mobile terminal is disclosed for determining whether or not to transmit a connection request for a connection between the mobile terminal and a base station, where the base station is moving. When the mobile terminal is detecting the base station, the mobile terminal is determining an indication of a relative speed between the mobile terminal and the detected base station. The mobile terminal is then determining whether or not to transmit the connection request to the base station. It is determined to transmit the connection request when the determined indication of the relative speed between the mobile terminal and the base station indicates that the relative speed is below a first threshold.

Abstract: A method in a base station is disclosed for determining connection establishment between the base station and a mobile terminal, where the base station is moving. When the base station receives a first connection request, the base station refrains from establishing a connection between the base station and the mobile terminal. When the base station receives a second connection request from the mobile terminal, the base station determines whether or not to establish the connection between the base station and the mobile terminal.

Abstract: A data processing system includes one or more processors that each execute one or more operating systems. Each operating system includes one or more applications. An accelerator provides a shared resource for a plurality of the applications and has one or more input/output interfaces for the submission of tasks to the accelerator from an application. A hypervisor manages the allocation of the input/output interfaces to the one or more operating systems and a hypervisor interface enables communication between the hypervisor and the accelerator. The system is capable of being configured such that an operating system that has been allocated an input/output interface is capable of communicating with the accelerator via the input/output interface independently of the hypervisor. A memory management unit is capable of providing an isolated region of a memory for use by the operating system while the operating system retains its allocated input/output interface.

Abstract: An apparatus for processing primitives in a tile-based graphics processing system includes processing circuitry which is configured to determine, for a group of plural primitives, the rendering tiles that the group of primitives should be processed for. The processing circuitry is also configured to store, for the group of primitives, a data entry containing an indication of the identity of the plurality of primitives in the group of primitives, and an indication of the rendering tiles that it has been determined the group of primitives should be processed for.

Abstract: A processing system comprises plural processing cores and a task allocator for allocating tasks to the processing cores. The processing cores perform the tasks that are allocated to them so as to produce results for the tasks, the results being stored by the processing cores in a buffer. The task allocator indicates to the processing cores memory portions within the buffer in which to store the results. When the processing cores determine that a given memory portion is becoming full, the processing cores request that the task allocator indicates a new memory portion in which to store its results. The processing system allows the task allocator to dynamically and efficiently allocate memory portions to plural processing cores without the task allocator 40 needing to know the sizes of the results being produced by the processing cores.
