Abstract: A data processing apparatus includes a memory and memory protection circuitry for providing an operational path to the memory during operational use of the memory. A memory built-in self-test controller 34 performs built-in self-test operations upon the memory using either an indirect test access path to the memory via the memory protection circuitry or a direct test access path to the memory which bypasses the memory protection circuitry. Thus, the correct operation of the memory protection circuitry itself can be tested in addition to the correct operation of the memory.

Abstract: A system and method for implementing storage management with threshold control is provided. A flexible storage manager associates storage devices having a similar performance characteristic into logical constructs called storage groups. Storage groups having the same performance characteristic from a plurality of storage systems are organized into storage pools. The flexible storage manager automatically provisions storage on a storage pool basis. Should a low threshold utilization be exceeded, the flexible storage manager performs a set of management policies to lower the utilization of a storage pool to the low threshold.

Abstract: Reset control circuitry is disclosed, for controlling a first reset signal for resetting at least a first portion of a circuit and a further reset signal for resetting at least a second portion of said circuit, said reset control circuitry comprising: an input for receiving an input first reset signal; an input for receiving an input further reset signal; an output for outputting an output first reset signal; and an output for outputting an output further reset signal; said reset control circuitry being responsive to detecting deassertion of said input first reset signal when said input further reset signal is asserted to delay deassertion of said output first reset signal so that said output first reset signal is deasserted at a same time or later than said input further reset signal.

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: A winged device has an axial support which is mounted for reciprocating rotary motion about a longitudinal axis of the support. A first wing vane is mounted to the axial support for rotation with the axial support. A second wing vane is mounted to the axial support. A cam follower is constrained to a defined movement path by a cam. A first connector connects the first wing vane to the cam follower such that the cam follower is moved along the cam by the first connector as the first wing vane moves with rotation of the axial support about its longitudinal axis. A second connector connects the second wing vane to the cam follower such that the second wing vane is moved by the second connector as the cam follower member is moved along the cam. The cam profile is defined relative to the axis of the axial support such that the relative orientation of the wing vanes changes as the axial support is rotated.

Abstract: Software built in self test computer programs 12 are generated using a genetic algorithm 14 technique. A fault simulator 20 is used to simulate candidate software built in self test computer programs and compare the simulated execution, such to deliberately introduced test faults, with expected execution outcomes previously derived for that candidate program to determine the sensitivity of that candidate program to the faults which are introduced. This score can be fed back into the genetic algorithm mutation to converge the mutation process upon appropriately fault sensitive software built in self test program code.

Abstract: A system is described having a JTAG diagnostic unit 2 and a serial wire diagnostic unit 4. A watcher unit 6 is connected to a data connection 14 shared between the diagnostic units 2, 4. Special patterns detected upon the shared data connection 14 serve to switch between diagnostic modes with respective ones of the diagnostic units 2, 4 becoming active.

Abstract: A drive assembly for use with a mechanical flying or walking device comprises an articulated member (7) having first and second portions (7a, 7b) arranged such that the portions move relative to each other, and a drive mechanism (9) for imparting motion to the articulated member. The drive mechanism (9) comprises: a drive member for imparting a cyclic motion on the articulated member, and a control member for controlling, in a predetermined manner, the relative position of the first and second portions during each cycle of the cyclic motion of the articulated member. In the case of a mechanical flying device, two such drive assemblies may be provided, the articulated member of each assembly forming a wing.

Abstract: Testing of the test signal connections to a functional block of circuitry within an integrated circuit is made using wrapper serial scan chain cells of a wrapper serial scan chain. These wrapper cells can then be used to validate that the correct signals are reaching test signal inputs and the correct signals are reaching their destination from test signal outputs when that functional block of circuitry is incorporated within a larger design, e.g., a system-on-chip design.

Abstract: A process for treatment of waste activated sludge from a BNR process, which includes the steps of: (a) concentration of the activated sludge from a total solids content (dry weight) of 0.1-1.0% w/v to an increased solids content of 1.5-5.0% w/v, wherein said solids largely contain bacterial biomass from prior aeration of the activated sludge; (b) disrupting bacterial cells contained in the biomass so as to release fermentable nutrients from said bacterial cells; (c) passing the activated sludge from step (b) through an anaerobic digester system; and (d) removing N and/or P from the residue obtained after step (c).

Abstract: The present invention provides a debugger interface unit for a data processing apparatus, comprising a control register having a number of fields, each field corresponding to a particular exception routine, and each field being settable to indicate that the debugger wishes to identify an access to the corresponding exception routine. Further, an exception routine catch logic is provided to receive a first signal when a processor core within the data processing apparatus issues an instruction fetch command for an exception routine, and to determine from an instruction address issued with the instruction fetch command which exception routine is being fetched. In addition, the catch logic is arranged to reference the field of the control register corresponding to the determined exception routine to determine if that field has been set, and if the field has been set, to output a breakpoint signal to the processor core.
