Abstract: Within an integrated circuit (2) independently controllable domains (4, 6, 8, 10, 5 12, 14) may be unable to complete pending transactions taking place between domains. Each domain is provided with a state machine (20, 22) which is responsive to the state of the state machine within the other domain and when this indicates that the other domain is not communicating triggers modified behavior. This can provide that the predetermined transaction protocol is not broken and/or complete a partially completed transaction when the domain concerned has recovered from an error or other event which disrupted the communication.

Abstract: A direct memory access controller for controlling data transfer between a plurality of data sources and a plurality of data destinations is disclosed. The plurality of data sources and data destinations communicate with the direct memory access controller via a plurality of channels, the direct memory access controller further communicates with a memory and a processor. The memory stores two sets of control data for each of the plurality of channels and for the processor. The direct memory access controller is responsive to a data transfer request received from one of said plurality of channels or from said processor to access one set of said corresponding control data stored in said memory, said direct memory access performing at least a portion of said data transfer requested in dependence upon said accessed control data.

Abstract: A remote switch actuator assembly includes a handle bar, a first actuator lever mounted to the handle bar, a mounting bracket configured to secure a drill to the handle bar such that a chuck end of the drill faces the handle bar, a second actuator lever secured to the mounting bracket so as to be in proximity with an actuation switch of the drill when the drill is secured by the mounting bracket, and a cable extending between and coupled with the first actuator lever and the second actuator lever. The first actuator lever is movable with respect to the handle bar to effect movement of the cable and corresponding movement of the second actuator lever toward the mounting bracket and the actuation switch of the drill when the drill is secured by the mounting bracket, and movement of the second actuator lever facilitates actuation of the drill secured by the mounting bracket by engaging with the actuation switch of the drill in response to movement of the first actuator lever.

Abstract: An apparatus for processing data includes diagnostic mechanisms for providing watch point and breakpoint functionality. Semaphores are associated with the watch points and are provided with hardware support within the diagnostic circuitry serving to monitor whether or not accesses to watch point data is being made in accordance with the permissions set up and noted in the semaphore data.

Abstract: A system is described having a JTAG diagnostic unit and a serial wire diagnostic unit. A watcher unit is connected to a data connection shared between the diagnostic units. Special patterns detected upon the shared data connection serve to switch between diagnostic modes with respective ones of the diagnostic units becoming active.

Abstract: The invention provides an improved method for obtaining information about DNA analysis of samples of uncertain origin by establishing the likelihood that they arose in certain manners compared with other possible manners. In this way all of the analysis information is taken into account and likelihood ratios are provided to express the results. The invention is particularly useful in analysing small DNA samples or DNA samples where the contribution from one or more sources is small.
