Playing cards having a deck divided into a first suit of threat cards and a second suit of tool cards. Play is conducted by each player concocting a story based on the cards, for instance, a defense, using what is shown on the tool card or cards the player has, against the threat shown on the threat card the player has. Points may be awarded for creativity in telling a story with the winner having the most points at the end of play, or alternatively, players may play for the fun of creating stories.

Dynamic fetch rate control for a prefetch unit 4 fetching program instructions from a pipelined memory system 2 is provided. The prefetch unit receives a fetch rate control signal from a fetch rate controller 8. The fetch rate controller 8 is responsive to program instructions currently held within an instruction queue 6 to determine the fetch rate control signal to be generated.

An engine mount for a gas turbine comprises a first compliant structure having a range of compliant movement governed by a first stiffness value. The mount further comprises stiffening means which act upon the compliant structure through part of the range of compliant movement such that the mount has at least two modes of operation, a first mode governed only by the first stiffness value of the compliant structure, and a second mode governed by both the first stiffness value and the stiffening means.

A table lookup extension instruction is provided in which index values stored within an index register D2 are used to select data elements stored within one or more table registers D0, D1 for storage into corresponding positions within a result register D3. Out-of-range index values result in the corresponding locations within the result register being left unchanged U. In this way, an offset can be applied to index values held and then those index values reused with the table registers D0, D1 being reloaded with a different portion of a table so as to give the effect of a larger table than can be directly supported by the number of table registers available.

The present invention provides a data processing apparatus and method for merging secure and non-secure data. The apparatus comprises at least one processor operable to execute a non-secure process to produce non-secure data to be included in an output data stream, and to execute a secure process to produce secure data to be included in the output data stream. A non-secure buffer is provided for receiving the non-secure data produced by the non-secure process, and in addition a secure buffer is provided for receiving the secure data produced by the secure process, the secure buffer not being accessible by the non-secure process. An output controller is then arranged to read the non-secure data from the non-secure buffer and the secure data from the secure buffer, and to merge the non-secure data and the secure data in order to produce a combined data stream, the output data stream then being derivable from the combined data stream. It has been found that such an approach assists in improving the security of the secure data, and in reducing memory bandwidth requirements and the processing requirements of the processor.

A liquid dispensing apparatus for dispensing droplets of a liquid, and methods for measuring various fluid parameters of the liquid are described. The liquid dispensing apparatus comprises a container having a chamber for holding a liquid. An orifice is positioned at an end of the chamber for dispensing droplets of the liquid, the orifice being configured to retain the liquid in the container if the container is positioned with the orifice facing in a downward direction. An acoustic transducer means is at least partially positioned in the chamber for periodically propagating a focused acoustic beam toward the orifice and through at least some of the liquid while the liquid is contained in the chamber, with the focused acoustic beam being capable of causing a droplet of the liquid to be ejected from the orifice when a free surface of the liquid is within the depth of field of the acoustic transducer means. Fluid parameters that can be measured include the sound velocity in the liquid, liquid level and liquid concentration, liquid acoustic impedance, liquid density and ultrasonic viscosity.

A test system, method and a computer program product are provided for testing software to be run on a data processing apparatus having a plurality of processors operable to share access to a memory system, where at least a part of the memory system has a memory ordering type which allows memory access requests at that part to be processed out of order from an original program order. The test system comprises a processor simulator for each processor of the data processing apparatus, each processor simulator being operable to execute a sequence of instructions in program order. Further, at least one access buffer unit is provided, each access buffer unit being associated with one of the processor simulators and being operable to receive memory access requests issued by that processor simulator when executing memory access instructions within the sequence of instructions. Each access buffer unit comprises at least one buffer operable to store memory access requests issued by the associated processor simulator, and a controller operable to apply an eviction policy to determine an order in which the memory access requests are output from the access buffer unit to the memory system. The eviction policy is configurable such that the memory ordering type of said part of the memory system is exercised to a degree exceeding that expected within the data processing apparatus, in order to seek to provoke an occurrence of any bug in the software resulting from an assumption of memory ordering which is not appropriate for the data processing apparatus.

A data processing apparatus and method are provided for moving data between registers and memory. The data processing apparatus comprises a register data store having a plurality of registers operable to store data elements. A processor is operable to perform in parallel a data processing operation on multiple data elements occupying different lanes of parallel processing in at least one of the registers. Access logic is provided which is responsive to a single access instruction to move a plurality of data elements between a chosen one of the lanes in specified registers and a structure within memory having a structure format, the structure format having a plurality of components. The single access instruction identifies the number of components in the structure format, and the access logic is operation to arrange the plurality of data elements as they are moved such that data elements of different components are stored in different specified registers within the chosen lane whilst in memory the data elements are stored as the structure.
摘要:
Disclosed herein are embodiments of combined cycle power plants having elevated exhaust pressure from a steam turbine. The elevated exhaust pressure from the steam turbine may result in an elevated condensate pressure and temperature. A cooling system removes sensible heat from the condensate. The elevated condensate temperature results in a greater temperature difference between the condensate and the working medium in the cooling system. The amount of heat that is dissipated by the cooling system is proportionate to the heat transfer surface and the temperature difference between the condensate and the working medium. As a result of the greater temperature difference, a smaller cooling system configured to operate with a higher temperature condensate may be utilized in place of a larger cooling system configured to operate with lower temperature condensate. By reducing the size of the cooling system, the overall size of the combined cycle power plant may be reduced.
