A method of operating a signal processing apparatus () comprises receiving a first signal representing a received data bit, determining from the first signal a first soft data bit, storing the first soft data bit in a leaky storage device (), receiving a second signal representing the received data bit, and determining from the second signal a second soft data bit. The stored first soft data bit is read from the leaky storage device (), an elapsed leakage time of the stored first soft data bit is measured, and a third soft data bit is generated dependent on the stored first soft data bit read from the leaky storage device () and on the elapsed leakage time. A fourth soft data bit is generated by combining the second soft data bit and the third soft data bit, and the received data bit is decoded dependent on the fourth soft data bit and on a selected plurality of further received data bits.

Signal processing apparatus and method

A SIM selection method of a wireless communication device connectable to a first SIM associated with a first subscription in relation to a first wireless communication system and a second SIM associated with a second subscription in relation to a second wireless communication system. The method comprises obtaining current values of first second and third parameters. The first parameters are applicable in relation to the first SIM and in relation to the second SIM, and comprise a geographical location of the wireless communication device. The second and third parameters obtained for the first SIM are applicable in relation to the first SIM only and the second and third parameters obtained for the second SIM are applicable in relation to the second SIM only. The current values of the third parameters are based on values of the third parameters associated with the geographical location and uploaded to a server by a plurality of other wireless communication devices. The method also comprises receiving a SIM utilization request from an application of the wireless communication device and selecting one of the first SIM and the second SIM for utilization by the application based on the current values of the first parameters, the second parameters, and the third parameters. Corresponding computer program product, SIM selector and wireless communication device are also disclosed.

SIM selection

A computing device includes at least one master unit; at least one slave unit; an interconnect structure configured to route transactions from the at least one master unit to the at least one slave unit; and a transaction logger device configured to intercept and save a record of outstanding transactions sent by the at least one master unit to the interconnect structure. The transaction logger device is further configured to preserve the record of outstanding transactions when at least a part of the computing device is restarted.

Method, system and architecture for bus transaction logger

A method in a Just-In-Time, JIT, compiler for compiling code in a JIT-compiler for a heterogeneous multiprocessor system is provided. The method comprises compiling a snippet of input code, whereby one or more compiled code snippets are generated for the snippet of input code. The one or more compiled code snippets are tagged with one or more snippet specific characteristics. One or more compiled code snippets are selected from the compiled code snippets, based on said snippet specific characteristics. The one or more selected compiled code snippets are executed on one or more of the plurality of processors. While executing, run-time data is gathered, where the gathered data is tagged for which processor in the heterogeneous multiprocessor system it is related to.

Methods for compilation, a compiler and a system

A method in a first device for anonymously delivering data to a part that has initiated a task is provided. The first device and the part initiating a task are participants in opportunistic sensing. The method comprises creating a data sample and encrypting the data sample with a public key of the task initiating part. After communicating the protected sample to one or more intermediate devices, one of the one or more intermediate devices delivers the protected sample to the task initiating part, such that the task initiating part does not know the identity of the first device. The task initiating device only know the identity of the one of the one or more intermediate devices that delivered the protected sample to the task initiating part, wherein the intermediate devices are participants in the opportunistic sensing.
