Abstract: When executing a program on a data processor comprising an execution unit for executing instructions in a program to be executed by the data processor, the execution unit being associated with one or more hardware units operable to execute instructions, at least one instruction in a program is associated with an indication of whether the instruction should be issued directly for execution by a hardware unit or should be intercepted during its execution by the execution unit. The execution unit then, when decoding the instruction for execution by a hardware unit in the program, determines from the indication associated with the instruction whether the instruction should be issued directly for execution by a hardware unit or intercepted during its execution by the execution unit, and issues the instruction for execution by a hardware unit directly, or pauses execution of the instruction and performs another operation, accordingly.

Abstract: According to some embodiments, a method performed by a wireless device for receiving paging information comprises receiving a paging message from a network node. The paging message includes a paging indicator associated with a plurality of wireless devices (e.g., group paging message). The method further comprises determining the wireless device is associated with the paging indicator, transmitting a random access request message to the network node, and receiving a random access response message from the network node. The random access response message is associated with a radio network temporary identifier (RNTI). The method further comprises determining, based on the RNTI, that the random access response includes additional paging information for the wireless device, and decoding the random access response.

Abstract: A data processing system in which a host processor prepares command streams for causing an accelerator of the data processing system to perform processing tasks for an application executing on the host processor, each command stream including a sequence of commands for implementation by the accelerator. When a request for processing includes protected content, the host processor includes within a command for a command stream, an indication that a subsequent sequence of one or more command(s) within that command stream associated with the protected content is to be implemented by the accelerator in a protected mode of operation. Then, when that command is executed, the accelerator initiates or requests a switch into the protected mode of operation.

Abstract: According to a first aspect of embodiments herein, the object is achieved by a method performed by a User Equipment, UE, for handling a paging message in a wireless communications network. The UE configures (201) the UE to derive a group paging identifier to be associated with the UE from a first identifier associated with the UE, and to use the derived group paging identifier for identifying group paging identifier matches in response-driven paging, irrespective of UE state and initiator of the paging. The UE receives (202) a paging message from the wireless communications network. The paging message comprises the group paging identifier associated with the UE. The UE then derives (203) the group paging identifier associated with the UE from the first identifier associated with the UE. By means of the derived group paging identifier the UE identifies (204) group paging identifier matches in response-driven paging, irrespective of said UE states and initiator of the paging.

Abstract: Apparatuses and methods for address translation invalidation are provided. In an apparatus having address translation storage which stores merged address translation information for multiple address translation stages, a set of counters are provided to hold a set of counter values. Entries in the address translation storage are stored with identifiers of first and second counters selected from the set of counters in dependence on respective context information for a first stage and a second stage of address translation together with a counter value of each counter. In response to an invalidation request specifying a first or second addressing scheme invalidation context a counter of the set of counters is selected in dependence on the first or second addressing scheme invalidation context and its value is modified.

Abstract: A data processing system comprises one or more data processing units, a configurable interconnect and control circuitry. The control circuitry allocates one or more of the data processing units to a virtual machine and configures the configurable interconnect so as route one or more data processing tasks from the virtual machine to the one or more data processing units allocated for use by that virtual machine. This can provide a flexible and adaptable data processing system for carrying out the data processing tasks of a virtual machine, with the particular allocation of data processing units being substantially transparent to the virtual machine.

The data processing system also includes a mechanism for switching the accelerator from its normal mode of operation to the protected mode of operation, and from its protected mode of operation to the normal mode of operation.

Abstract: Methods and arrangements for managing a retransmission on a Random Access CHannel, “RACH”, in a wireless communication network (100). A device (600; 120) performs (404; 502) the retransmission on the RACH, wherein the retransmission is based on a coverage class associated with the device (600; 120). Basing the retransmission on the coverage class e.g. enables reduction of retransmission collisions when the wireless communication network (100) operates as in Extended Coverage GSM, “EC-GSM”.

Abstract: When a processing resource of a data processing system is to perform processing tasks for applications executing on a host processor, the host processor prepares a plurality of command streams to cause the processing resource to perform the processing tasks. When a processing task to be added to a command stream has a dependency on a processing task or tasks that will be included in another command stream, a wait command is added to the command stream that is to include the processing task that has a dependency on a processing task or tasks that will be included in the another command stream, to cause the processing resource to delay executing subsequent commands in the command stream after the wait command, until the processing resource has reached a particular position in the another command stream.
